Weight loss: In a study to determine whether counseling could help people lose weight, a sample of people experienced a group-based behavioral intervention, which involved weekly meetings with a trained interventionist for a period of six months. The following data are the numbers of pounds lost for 14 people. Assume the population is approximately normal. Perform a hypothesis test to determine whether the mean weight loss is greater than 17 pounds. Use the α=0.05 level of significance and the P-value method with the TI-84 Plus calculator. 22.3 28.2 7.3 23.7 21.2 12.6 17.1 20.8 37.3 33.5 11.8 36.1 23.7 19.2

Part C, D and E please, Thank You! D) What is the null hypothesis? E) Reject the null hypothesis because the P-value is greater than the significant level, a Reject the null hypthosesis because the P-value is less than or equal to the significant level, a Fail to reject the null hypothesis because the P-value is greater than or equal to the significant level, a Fail to reject the null hypothesis because the P-Value is greater than the significant level, a

Part I. Constructing a Null and Alternative Hypothesis: Write a pair of null and alternative statistical hypothesis (can be about any topic).
Assume that adults were randomly selected for a poll. They were asked if they "favor or oppose using federal tax dollars to fund medical research using stem cells obtained from human embryos." Of those polled, 484 were in favor, 397 were opposed, and 123 were unsure. A politician claims that people don't really understand the stem cell issue and their responses to such questions are random responses equivalent to a coin toss. Exclude the 123 subjects who said that they were unsure, and use a 0.10 significance level to test the claim that the proportion of subjects who respond in favor is equal to 0.5. What does the result suggest about the politician's claim? Identify the null and alternative hypotheses for this test. Choose the correct answer below. А. Но: р3D0.5 H4:p>0.5 В.

Assume that adults were randomly selected for a poll. They were asked if they "favor or oppose using federal tax dollars to fund medical research using stem cells obtained from human embryos."

A politician claims that people don't really understand the stem cell issue and their responses to such questions are random responses equivalent to a coin toss. Exclude the 124 subjects who said that they were unsure, and use a 0.01 significance level to test the claim that the proportion of subjects who respond in favor is equal to 0.5.

Assume that adults were randomly selected for a poll. They were asked if they "favor or oppose using federal tax dollars to fund medical research using stem cells obtained from human embryos." Of those polled, 485 were in favor, 397 were opposed, and 115 were unsure. A politician claims that people don't really understand the stem cell issue and their responses to such questions are random responses equivalent to a coin toss. Exclude the 115 subjects who said that they were unsure, and use a 0.01 significance level to test the claim that the proportion of subjects who respond in favor is equal to 0.5.
