Suppose we run a two sample t-test using consumer ratings on two robotic vacuums, which are labelled "Sting-Ray" and "E-Vac," but they are actually the same model vacuum. The null hypothesis for the test is H0: μS = μE. If we reject this null hypothesis, we have evidence of brand preference among consumers of robotic vacuums.
tRUE OR FALSE
Homework Answers
True .
Since null hypothesis states that the rating of both vacuums are same. But observations indicate otherwise and there is evidence of significant difference in the ratings of the two on the basis of which, we reject the null hypothesis.

Suppose we do not reject the t-test null hypothesis of H0: β1 = 0 for a regression. In this case, we think there is evidence that the X variable values help explain the Y variable values. True or False

Consider a two sample t-test, where the sample mean of A = 5.3 and the sample mean of B = 2.9. The margin of error is 1.6, and the null hypothesis is H0: μA = μB. In this case, we do not reject the null hypothesis. True or false

Twelve runners are asked to run a 10-kilometer race on each of two consecutive weeks. In one of the races, the runners wear one brand of shoe and in the other, a different brand. The brand of shoe they wear in each race is determined at random. All runners are timed and are asked to run their best in each race. The results (in minutes) are given below.

The one-sample t statistic from a sample of n = 21 observations for the two-sided test of H0: μ = 60, Ha: μ ≠ 60 has the value t = –1.98. Based on this information: we would reject the null hypothesis at α = 0.05. All of the answers are correct. 0.025 < P-value < 0.05. we would reject the null hypothesis at α = 0.10

A blind taste test is conducted to determine which of two colas, Brand A or Brand B, individuals prefer. Individuals are randomly asked to drink one of the two types of cola first, followed by the other cola, and then asked to disclose the drink they prefer. Results of the taste test indicate that 48 of 100 individuals prefer Brand A. Complete parts a through c. Do not reject the null hypothesis for the values of po between 0.39...
