A researcher administers a treatment to a sample of participants selected from a population with µ = 80. If a hypothesis test is used to evaluate the effect of the treatment, which combination of factors is most likely to result in rejecting the null hypothesis?
a. a sample mean near 80 with a=.05b. a sample mean much different than 80 with a=.05c. a sample mean much different than 80 with a=.01d. a sample mean near 80 with a=.01
Answer:
The answer is "Option c"
Step-by-step explanation:
In the given question, in choice c the numerice value is missing, that is "0.05".
The null hypothesis can only be rejected whether there is enough statistical data than that of the critical values.
The options A and B are not accurate, because the mean test of around 80 means that now the check-in and check number is lower, giving small statistics of the experiment and resulting in the null hypothesis is not rejected. In the C or D is true, however, the importance or alpha level need to be tested Alpha level 0.05 is 5% likely to reject an absolute zero hypothesis so, although 0.01 alpha level is 1% more likely to oppose an absolute zero hypothesis, Therefore, the alpha 0.05 rating is stronger.`.

Heidi is riding her bike to visit a friend in another town. Her speed is inversely related to her travel time. If she is Charlie at 15 mph it will take her for hours to reach her destination. How long will it take her if she travels at 12 mph?
Step-by-step explanation:
I am not sure I understand the question with all the typos and potentially missing parts.
as I understand it, it will take her 4 hours to reach her destination when going 15 mph.
and the question is how long the trip will take, if she travels at 12 mph.
4 h × 15 m/h = 4 × 15 m = 60 miles
that is the distance of her trip.
when going slower, the distance is of course still the same, only the needed time changes :
x h × 12 m/h = 60 m
x × 12 m = 60 m
x = 60/12 = 5 hours
the trip would take her 5 hours to complete (instead of 4).

HELPP! The perimeter of a rectangle is 104 inches. The width is 6 inches less than 3 times the length. Find the
width of the rectangle.Show each step and explain what was performed for each step.
Answer:
Length of the rectangle = 14.5 inches
Width of the rectangle = 37.5 inches
Step-by-step explanation:
Let the length of a rectangle = a inches
Since, width of the rectangle is 6 inches less than 3 times the length,
w = 3a - 6
Perimeter of the rectangle = 104 inches
Formula to calculate the perimeter of a rectangle = 2(length + width)
104 = 2[a + (3a - 6)]
2a + 2(3a - 6) = 104 → [Starting equation]
8a - 12 = 104 → [Distributive property]
8a - 12 + 12 = 104 + 12 → [Addition property of equality]
a = [tex]\frac{116}{8}=14.5[/tex] → [Division property of equality]
a). width of the rectangle = (3a - 6) = 37.5 inches
b). length of the rectangle = 14.5 inches
The width of the rectangle is 37.5 inches and the length of the rectangle is 14.5 inches.
The perimeter of a rectangle is represented as follows:
perimeter = 2l + 2w
where
w = width
l = length
Therefore,
perimeter = 104 inches
let
the length = a
Therefore,
width = 3a - 6
Therefore,
104 = 2a + 2(3a - 6)
104 = 2a + 6a - 12
116 = 8a
a = 116 / 8
a = 14.5 inches
width = 3(14.5 ) - 6 = 37.5 inches
Therefore, the width of the rectangle is 37.5 inches and the length of the rectangle is 14.5 inches.

First of all, lets cut the shape into two. A rectangle and a triangle. This will help us find the slanted side of the shape.
We will use the pythagorean theorem to find the length of the slanted line.
The pythagorean theorem is [tex]a^{2} +b^{2} =c^{2}[/tex].
Input the given information of the triangle lengths that we know; that is the length= 6 and the base=3.
[tex]c= \sqrt{a^{2}+b^{2} } =\sqrt{6^{2}+\ 3^{2} } = 6.7082[/tex]
Now, we round.
6.7082≈ 6.7
We have found the length of the slanted line of the shape.
Now, let's add all the lengths together.
8+6+6.7+11= 31.7
Now, lets round.
31.7 ≈ 32cm
