The  interval means that there is 90% confidence that the true difference between the proportion of Vioxx users who suffered from heart attack  and the non-Vioxx users (the placebo group  ) who suffered from heart attack  lie within the interval

The  use of Vioxx drug should be stopped

Step-by-step explanation:

From the question we are told that

   The sample size for Vioxx users is  [tex]n_1 = 3025[/tex]

   The second sample size for placebo is  [tex]n_2 =  2875[/tex]

   The number of Vioxx users that suffered heart attack is  [tex]k  = 334[/tex]

     The number of non-Vioxx users that suffered heart attack is  [tex]g  = 272[/tex]

    Generally the  sample proportion for Vioxx users is mathematically represented as

      [tex]\r p_1 =  \frac{k}{n_1}[/tex]

=>   [tex]\r p_1 =  \frac{334}{3025}[/tex]

=>   [tex]\r p_1 =  0.11041 [/tex]

    Generally the  sample proportion for placebo users is mathematically represented as

       [tex]\r p_2 =  \frac{g}{n_2}[/tex]

=>   [tex]\r p_2 =  \frac{272}{2875}[/tex]

=>   [tex]\r p_2 =  0.09461 [/tex]  

Generally the confidence level is 90% , then the level of significance is  [tex]\alpha =  (100-90)\%[/tex]

=>   [tex]\alpha =  0.10[/tex]

Generally the critical value of  [tex]\frac{\alpha }{2}[/tex] from the normal distribution table  is  

     [tex]Z_{\frac{\alpha }{2} } =  1.645[/tex]

Generally the standard error is mathematically represented as

      [tex]SE =  \sqrt{\frac{\r p_1 (1- \r p_1)}{n_1} + \frac{\r p_2 (1- \r p_2)}{n_2} }[/tex]

=>  [tex]SE =  \sqrt{\frac{0.11041 (1- 0.11041)}{3025} + \frac{0.09461 (1-0.09461)}{2875} }[/tex]

=>  [tex]SE = 0.0079[/tex]

Generally the margin of error is mathematically represented as

    [tex] E=  Z_{\frac{\alpha }{2} } *  SE[/tex]

=>  [tex] E=  1.645  *  0.0079[/tex]  

=>  [tex] E=  0.013[/tex]  

Generally the 90%  confidence interval is mathematically represented as

     [tex]0.11041 - 0.09461- 0.013 < p_1 - p_2  < 0.11041 - 0.09461+ 0.013 [/tex]

=>       [tex]0.0028  < p_1 - p_2  < 0.0288[/tex]

The  interval means that there is 90% confidence that the true difference between the proportion of Vioxx users who suffered from heart attack  and the non-Vioxx users (the placebo group  )  lie within the interval

Looking at the interval we see that proportion of Vioxx users who suffered is  more compared to  non-Vioxx users (the placebo group  )[i.e the both limit of the interval is  positive ] hence the  use of Vioxx drug should be stopped

Answer:

y=-2/3x+10 1/3

Step-by-step explanation:

y=mx+b (m = slope)

(Equation) y2-y1/x2-x1

= 6-0/-5-4

= -6/9

= -2/3

y-y1 = m(x-x1)

y-6 = -2/3 +5

y-6 = 4 1/3

y = 10 1/3

Answer:

Step-by-step explanation:

You pay $350 to Grandma.

What is Multiplication?

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

Grandma  pays upfront for you to go on an overnight trip with the school, which costs $340.

And, You make a deal that you’ll give her $25 per month until you pay it all back.

Now,

Let the number of months to pay Granma = x

Then, we can formulate;

$25x = $340

x = 13.6

After rounding,

x = 14

So, We pay 14 months to grandma;

Hence, The cost to pay grandma in 14 months = 14 x $25

                                                                        = $350

Therefore, You pay $350 to Grandma.

The difference between the range will be 5.

When the sample maximum and minimum are subtracted, the range of a collection of data is the difference between the greatest and lowest values. It uses the same units as the data to express itself.

Given that last year, the highest value of temperature is 29 and the lowest is 6. After two years the maximum temperature is 25 and the lowest is 7.

The range difference will be calculated as,

Range = ( 29 - 6 ) - ( 25 - 7 )

Range = ( 23 - 18 )

Range = 5

Answer:

The value of x is 63° ⇒ B

Step-by-step explanation:

The rule for finding the sum of the interior angles of a polygon with n sides is S = (n - 2) × 180°

In the given figure

There is a polygon with 5 sides

∵ n = 5

∴ S = (5 - 2) × 180°

∴ S = 3 × 180°

∴ S = 540°

→ We have the measure of 4 angles of them    

∵ The sum of the 4 given angles =  119° + 100° + 88° + 116°

∴ The sum of the 4 given angles = 423°

→ To find the 5th angle subtract 423° from 540°

∵ The measure of the fifth angle = 540° - 423°

∴ The measure of the fifth angle = 117°

→ x and 117° are linear pair angles, then their sum is 180°

∵ x + 117° = 180° ⇒ linear pair angles

→ Subtract 117 from both sides to find x

∴ x + 117 - 117 = 180 - 117

∴ x = 63°

Answer:

d

Step-by-step explanation:

The probability of obtaining a simple random sample of 20 students whose mean IQ score is greater than 108 is

    [tex]P(\= X > 108) = 0.0084242[/tex]

B

Comparing the p-value obtained with a low level of significance  (say ∝= 0.01 ) we see that the p-value  is  less than ∝ which implies that the null hypothesis is  rejected hence  we can state that there is sufficient evidence to conclude that the mean IQ for all students at the school is greater than 100

Step-by-step explanation:

From the question we are told that

  The standard deviation is  [tex]\sigma = 15[/tex]

  The population mean is  [tex]\mu = 100[/tex]

  The sample size n  =  20

Generally the standard deviation of the sample mean (standard error ) is mathematically represented as

      [tex]\sigma_{\= x} = \frac{\sigma }{\sqrt{n} }[/tex]

=>   [tex]\sigma_{\= x} = \frac{15 }{\sqrt{20} }[/tex]

=>   [tex]\sigma_{\= x} = 3.35[/tex]

Generally the probability of obtaining a simple random sample of 20 students whose mean IQ score is greater than 108 is mathematically represented as

      [tex]P(\= X > 108) = P(\frac{\=X - \mu}{\sigma_{\= x} } > \frac{108 - 100}{3.35} )[/tex]

=>   [tex]P(\= X > 108) = P(Z > \frac{108 - 100}{3.35} )[/tex]

=>   [tex]P(\= X > 108) = P(Z > \frac{108 - 100}{3.35} )[/tex]

=>   [tex]P(\= X > 108) = P(Z >2.39 )[/tex]

From the z-table  

      [tex]P(z > 2.39) = 0.0084242[/tex]

So

      [tex]P(\= X > 108) = 0.0084242[/tex]

The null hypothesis is  [tex]H_o : \mu = 100[/tex]

The alternative hypothesis is  [tex]H_a : \mu > 100[/tex]

The sample mean is  [tex]\= x = 108[/tex]

Generally the test statistics is  =  2.39

  Generally the p-value is  equal  to 0.0084242

Now comparing the  p-value with a low level of significance  (say ∝= 0.01 ) we see that the p-value  is  less than ∝ which implies that the null hypothesis is  rejected  and we can conclude that there is sufficient evidence to conclude that the mean IQ for all students at the school is greater than 100
