Answer #1

one sample t-test is used to test if mean weight of chicks is greater than 120

Alternative hypothesis: >120

Level of significance = 0.01

Confidence level = 0.99

Input is given as above, then output is printed

t= 15.251

p-value is less than 0.01 level of significance, we reject null hypothesis and we accept alternative hypothesis

Conclusion: Mean weight of chicks is greater than 120

8. We know that the mean weight of men is greater than the mean weight of women, and the mean height of men is greater than the mean height of women. A person’s body mass index (BMI) is computed by dividing weight (kg) by the square of height (m). Use α = 0.05 significance level to test the claim that females and males have the same mean BMI. Below are the statistics for random samples of females and males. Female...
