According to Hypothesis Testing Procedure, to test a hypothesis (H1) one needs to first state the corresponding null hypothesis (H0) to later see if they should reject or fail to reject the null hypothesis. True or False
Homework Answers

State your decision to the significance test in terms of the null hypothesis. According to a recent poll, the percentage of Americans who would vote for the incumbent president is 53%. If a random sample of 100 people in New York results in 45% who would vote for the incumbent, test the claim that the percentage of people in New York who would vote for the incumbent president is different from 53%. Use the following results and a 0.10 significance...

(a) Suppose the null and alternative hypothesis of a test are: H0: μ= 9.7 H1: μ >9.7 Then the test is: left-tailed two-tailed right-tailed (b) If you conduct a hypothesis test at the 0.02 significance level and calculate a P-value of 0.07, then what should your decision be? Fail to reject H0 Reject H0 Not enough information is given to make a decision

A researcher in interested in whether students who are musicians have higher intelligence test scores than students in the general population. The mean for the general population is 100. The researcher selects 30 musicians from local high schools and gives them an intelligence test, with a mean of 105. SS = 725 for the sample. m = _______ M = _________ n = _______ s2...

help with this hypothesis testing procedure?
A manufacturing firm needs to test the null hypothesis Ho that the probability p of a defective item is 0.2 or less, against the alternative hypothesis H,: p 0.2. The procedure is to select four items at random. If all four items are defective, Ho is rejected; otherwise, a fifth item is selected. If the fifth item is defective, Ho is rejected. In all other cases, Ho is accepted. What is the power of...

True or False The model used for hypothesis testing of proportions is called a two-proportion z-test. True or False Beta (β) is the significance level which determines if the null hypothesis is rejected. True or False In business, the p-value is one of several factors in determining whether or not to reject a null hypothesis. True or False We could make a decision to reject a null hypothesis on a very low p-value or a very high z score.

On your first day on the job, your boss asks you to conduct a hypothesis test about the mean dwell time of a new type of UAV. Before you arrived, an experiment was conducted on ? = 5 UAVs (all of the new type) resulting in a sample mean dwell time of ?1 = 10.4 h????. The goal is to conclusively demonstrate, if possible, that the data supports the manufacturer’s claim that the mean dwell time is greater than 10...
