Suppose that in a random selection of 100 colored candies, 22% of them are blue. The candy company claims that the percentage of blue candies is equal to 28%. Use a 0.01 significance level to test that claim. Identify the null and alternative hypotheses for this test. Choose the correct answer below. A. H0: p≠0.28 H1: p=0.28 B. H0: p=0.28 H1: p>0.28 C. H0: p=0.28 H1: p<0.28 D. H0: p=0.28 H1: p≠0.28 Identify the test statistic for this hypothesis test. The test statistic for this hypothesis test is nothing. (Round to two decimal places as needed.) Identify the P-value for this hypothesis test. The P-value for this hypothesis test is nothing. (Round to three decimal places as needed.) Identify the conclusion for this hypothesis test. A. Reject H0. There is not sufficient evidence to warrant rejection of the claim that the percentage of blue candies is equal to 28% B. Reject H0.…
3. A claim is made that the proportion of college students who have Netflix accounts is 0.85. Noah believes this claimed value is too high. He is able to survey a random sample of 240 college students, and he finds that the sample proportion who have Netflix accounts is 0.82. Noah proceeds to use this data to conduct a hypothesis test. Based on this information, which one of the following statements is correct? A. The p-value will be smaller than 0.01 but larger than 0. B. The p-value will be between 0.01 and 0.05. C. The p-value will be between 0.05 and 0.10. D. The p-value will be larger than 0.10.
A publisher reports that 67% of their readers own a particular make of car. A marketing executive wants to test the claim that the percentage is actually different from the reported percentage. A random sample of 250 found that 62% of the readers owned a particular make of car. State the null and alternative hypotheses. what is HO and HA ?
A company that has a 10% market share (they sell their product to 10% of all potential buyers) launches a marketing campaign. At the end of the campaign period, the company conducts a survey in order to assess whether its market share has increased. The result of the survey issued to 500 customers was 12.5%.a. Write the null and alternative hypotheses using proper notation? b. What is the value of the test statistic? Show your work.c. What is the associated P-value? d. State your conclusion using ΅ = 0.05. e. What would be the potential Type I and Type II errors in this problem? Explain these possible errors in context.
Stay safe and healthy. Exercise: Apply the procedure in testing the hypothesis. A survey was conducted at a community college of 102 randomly selected students who dropped a course in the current semester to learn why students drop courses. Personal drop reasons include financial, transportation, family issues, health issues, and lack of child care. Course drop reasons include reducing ones load, being unprepared for the course, the course was not what was expected, dissatisfaction with teaching, and not getting the desired grade. Work drop reasons include an increase in hours, a change in shift, and obtaining full-time employment. Test whether gender is independent of drop reason at the 1% level of significance.

1) The percentage of complete passes is an important measure for a quarterback in the NFL. A particular quarterback has a career completion percentage of 55%. The quarterback got a new coach and then played a few games where he completed 48 of 100 passes. a. Specify the null and alternative hypotheses to determine whether the proportion of completed passes has decreased with the new coach. b. Calculate the value of the test statistic and the p-value. c. At the 5% significance level, can you conclude that the quarterback's completion percentage has decreased?
a. Let p denote the population proportion of correct hand selections by touch therapists. Identify the null and alternative hypotheses to test the claim that touch therapists use a method equivalent to random guesses. b. Identify the test statistic. c. Identify the P-value. d. State the conclusion about the null hypothesis, as well as the final conclusion that addresses the original claim. Address whether the results suggest that touch therapists are effective.

Dr. Kijowski is concerned about student phone use, so she collects information on the number of text messages that each student sent on a particular day. The boxplot below shows the results. Based on the boxplot, which of the following is the most reasonable conclusion? a. There are more people with data values below the median than there are people with data values above the median. Selected:b. There are more people with data values between the first quartile and the median than there are people with data values between the median and the third quartile.This answer is incorrect. c. There are fewer people with data values between the first quartile and the median than there are people with data values between the median and the third quartile. d. There are approximately the same number of people with data values between the first quartile and the minimum as there are people with data values between the third quartile and the maximum. e. The data are less spread out between the…
