The CEO of a large electric utility claims that at least 80 percent of his onemillion customers are very satisfied with the service they receive. A localnewspaper surveyed 300 customers randomly. 73 percent said they were verysatisfied. At a=0.01, is there enough evidence to support the claim?There is enough evidence to reject the null hypothesis. The claim is true.There is enough evidence to reject the null hypothesis. The claim is false.O There is not enough evidence to reject the null hypothesis. The claim is probably true.O There is not enough evidence to reject the null hypothesis. The claim is probably false.

A decade-old study found that the proportion of high school seniors who felt that "getting rich" was an important personal goal was 72% . Suppose that we have reason to believe that this proportion has changed, and we wish to carry out a hypothesis test to see if our belief can be supported. State the null hypothesis H0 and the alternative hypothesis H1 that we would use for this test. H0 : H1 :
At a high school debate tournament, half of the teams were asked to wear suits and ties and the rest were asked to wear jeans and T-shirts. The results are given in the table below. In order to test the claim at the 0.05 level that the proportion of wins is the same for teams wearing suits as for teams wearing jeans, what would the null hypothesis be? Win Loss Suit 22 28 T-Shirt 28 22 O A. The proportions of wins is different for teams wearing suits as for teams wearing jeans. O B. The proportions of wins is the same for teams wearing suits as for teams wearing jeans. O C. The mean number of wins is the same for teams wearing suits as for teams wearing jeans. O D. The mean number of wins is different for teams wearing suits as for teams wearing jeans.
A recent drug survey showed an increase in the use of drugs and alcohol among local high school seniors as compared to the national percentage. Suppose that a survey of 100 local seniors and 100 national seniors is conducted to see if the proportion of drug and alcohol use is higher locally than nationally. Locally, 65 seniors reported using drugs or alcohol within the past month, while 60 national seniors reported using them. Conduct a hypothesis test at the 5% level.NOTE: If you are using a Student's t-distribution for the problem, including for paired data, you may assume that the underlying population is normally distributed. (In general, you must first prove that assumption, though.) Part (a) State the null hypothesis. H0: plocal ≠ pnational H0: plocal > pnational H0: plocal = pnational H0: plocal < pnational Part (b) State the alternative hypothesis. Ha: plocal < pnational Ha: plocal = pnational Ha: plocal ≠ pnational Ha: plocal > pnational…
A medical researcher claims that the proportion of people taking a certain medication that develop serious side effects is 12%. To test this claim, a random sample of 900 people taking the medication is taken and it is determined that 93 people have experienced serious side effects.. The following is the setup for this hypothesis test: Ho :p 0.12 Ha p 0.12 In this example, the p-value was determined to be 0.124. come to a conclusion and interpret the results for this hypothesis test for a proportion (use a significance level of 5%) Select the correct answer below: The decision is to reject the Null Hypothesis. The conclusion is that there is enough evidence to reject the claim O The decision is to fail to reject the Null Hypothesis. The conclusion is that there is not enough evidence to reject the claim
53% of students entering four-year colleges receive a degree within six years. Is this percent larger than for students who play intramural sports? 161 of the 283 students who played intramural sports recelved a degree within six years. What can be concluded at the level of significance of a = 0.05? a. For this study, we should use Select an answer b. The null and alternative hypotheses would be: Ho: ? ♥ Select an answer ♥ (please enter a decimal) H: ?♥ Select an answer ♥ |(Please enter a decimal) C.

Based on this, we should| Select an answerv the null hypothesis. g. Thus, the final conclusion is that ... The data suggest the populaton proportion is significantly larger than 53% at a = 0.05, so there is sufficient evidence to conclude that the population proportion of students who played intramural sports who received a…

In a recent Super Bowl, a TV network predicted that 36 % of the audience would express an interest in seeing one of its forthcoming television shows. The network ran commercials for these shows during the Super Bowl. The day after the Super Bowl, and Advertising Group sampled 102 people who saw the commercials and found that 33 of them said they would watch one of the television shows.Suppose you are have the following null and alternative hypotheses for a test you are running:H0:p=0.36H0:p=0.36Ha:p<0.36Ha:p<0.36Calculate the test statistic, rounded to 3 decimal places z=z=

A flight attendant selects a random sample of 201 travelers. For each, he records the class in which the person travels and whether they have carry-on luggage. He would like to know if there is convincing evidence that the class in which a person travels is associated with having carry-on luggage. Let a = 0.05. What are the hypotheses for this test? O Ho: Class is not independent of carry-on luggage. Hg: Class is independent of carry-on luggage. O Họ: Class is independent of carry-on luggage. Hg: Class is not independent of carry-on luggage. O Họ: There is an association between class and carry-on luggage. Hạ: There is no association between class and carry-on luggage. O Ho: The proportion of travelers who have carry-on luggage is not the same in the types of class. Hg: The proportion of travelers who have carry-on luggage is the same in the types of class.
