engineers want to design seats in commercial aircraft so that they are wide enough to fit 99% of all males. men have hip breadths that are normally distributed with a mean of 14.4 in. and a standard deviation of 0.9 in. find p99. that is, find the hip breadth for men that separates the smallest 99% from the largest 1%.
Answer:
x = 16.45 inches
Step-by-step explanation:
Engineers want to design seats in commercial aircraft so that they are wide enough to fit 98% of all males. Men have hip breadths that are normally distributed with a mean of 14.4 inches and a standard deviation of 1 inch. find P98. I really don't understand, help needed please.
-----------------------
Find the z-value with a left tail of 0.98
invNorm(0.98) = 2.0537
-----
Find the corresponding x-value using x = zs+u
----
x = 2.0537*1+14.4
---
x = 16.45 inches

Final question - whats the answer?
Answer: 7^5 or 7 to the fifth power.
Step-by-step explanation: This is an exponent meaning you count the 7’s and in the first picture there’s 5 7’s. This means that the number your putting to a power is the yellow box so that’s 7 and the exponent is 5 not 4 because if you did 7 to the first power it’s still 7 so it would be 7 to the 5th power or 7^5

The mean monthly water bill for 44 residents of the local apartment complex is $104. What is the best point estimate for the mean monthly water bill for all residents of the local apartment complex?
Answer:
$104
Step-by-step explanation:
The computation of the best point estimate for the mean monthly water bill is shown below:
Given that
The mean monthly water bill is $104
and, the number of residents is 44
based on the above information
The best point estimate would be equivalent to the mean monthly water bill i.e. $104
hence, the same would be considered

A method currently used by doctors to screen for possible bre canc fails to detect canc in 15% of the women who actually have the disease. A new method has been developed that researchers hope will be able to detect canc more accurately. A random sample of 70 women known to have br canc were screened using the new method. Of these, the new method failed to detect can in six.
A. Specify the null and alternative hypothesis that the researchers wish to test.
B. Is the sample large enough
Step-by-step explanation:
1.sample size n = 70
X = 6
We calculate the sample proportion
P^ = 6/70
= 0.0857
The population proportion = 15 percent
P = 15/ 100
= 0.15
The question says we should specify the hypothesis
Null hypothesis
H0: p = 0.15
Alternative
H1: P < 0.15
2.
The sample size is 70 and therefore large enough
