Answer:
b. Do not reject the null hypothesis
Step-by-step explanation:
Given that two random samples of 40 students were drawn independently from two populations of students. Assuming equal variances
we have the following data.
Sample 1
Mean:
76
Standard deviation:
8
Sample size:
40
Sample 2
Mean:
73
Standard deviation:
7
Sample size:
40
Difference -3.000
Standard error 1.681
95% CI -6.3462 to 0.3462
t-statistic -1.785
DF 78
Significance level P = 0.0782
Since p value >0.05,
b. Do not reject the null hypothesis
Answer:
all work is shown and pictured
see the picture attached to better understand the problem
we know that
in the right triangle ABC
AB is equal to AC
BC is the hypotenuse
Applying the Pythagorean Theorem
therefore
the answer is
the length of the hypotenuse is units
