Manually compute for them first and then use computer software and thencompare your results.1. A teacher would like to know if the class will be able to absorb the lecture from a guest speaker, so he made them take a pre-quiz before the lecture and a post-quiz after the lecture.The teacher would like to know if there is a significant difference between the pre-quiz scores and the post-quiz scores of the students (note that they are in a specific order):1. Pre-quiz: 14,12,16,15,10,14,152. Post-quiz: 25,25,26,23,21,24,252. A student would like to know which establishment would allow him to save more money on everyday food costs. He is choosing between AVM or Hollywood Terraces, so he traced hisspending in both establishments for 1 school week each, his data is as follows:1. AVM: 97,85, 69, 105, 1052. HT: 60, 45, 60, 75, 100Find out if there is a significant difference in his spending between the two food courts.3.

A radio station states that 30% of the songs they play each week are from Canadian artists. A DJ working at the station claims that the actual percentage differs from what the station states. The DJ takes a random sample of 87 songs played during a given week and finds that 28 of them are from Canadian artists. Use this information to answer the questions below. a. Suppose the DJ wishes to perform a hypothesis test of his claim. Select the most appropriate null and alternative hypotheses for this hypothesis test. H0:p^≠0.3Ha:p^=0.3 H0:x―=0.3Ha:x―≠0.3 H0:μ≠0.3Ha:μ=0.3 H0:p=0.3Ha:p≠0.3 H0:μ=0.3Ha:μ≠0.3 H0:p≠0.3Ha:p=0.3 H0:p^=0.3Ha:p^≠0.3 H0:x―≠0.3Ha:x―=0.3 b. To assess his hypothesis, the DJ wants to compute a bootstrap-based confidence interval from his sample. Which of the following uses of the quantile() function would produce the correct interval bounds for a 96% bootstrap-based confidence interval? c(quantile(B$mean, 0.04), quantile(B$mean, 0.96)) c(quantile(B$mean, 0.02),…
In each part, we have given the significance level and the P-value for a hypothesis test. For each case determine if the null hypothesis should be rejected. Write "reject" or "do not reject" (without quotations - if you like use copy and paste to avoid typos). (a) α= 0.01, P = 0.06 answer: (b) a = 0.06, P = 0.001 answer: (c) a = 0.07, P = 0.06 answer:
At a nearby college, there is a school-sponsored website that matches people looking for roommates. According to the school's reports, 43% of students will find a match their first time using the site. A writer for the school newspaper tests this claim by choosing a random sample of 170 students who visited the site looking for a roommate. Of the students surveyed, 58 said they found a match their first time using the site. Complete the parts below to perform a hypothesis test to see if there is enough evidence, at the 0.10 level of significance, to reject the claim that the proportion, P, of all students who will find a match their first time using the site is 43%. (a) State the null hypothesis H, and the alternative hypothesis A that you would use for the test. P H 0 D=0 DO (b) For your hypothesis test, you will use a Z-test. Find the values of MP and n(1-p) to confirm that a Z-test can be used. (One standard is that Mp2 10 10 under the assumption that the null hypothesis is true.)…
Which of the following is NOT one of the steps for hypothesis testing? a. Verify data conditions and calculate a test statistic. O b. Assuming the alternative hypothesis is true, find the p-value. O c. Determine the null and alternative hypotheses. O d. Assuming the null hypothesis is true, find the p-value.
At a nearby college, there is a school-sponsored website that matches people looking for roommates. According to the school's reports, 39% of students will find a match their first time using the site. A writer for the school newspaper tests this claim by choosing a random sample of 160 students who visited the site looking for a roommate. Of the students surveyed, 54 said they found a match their first time using the site. Complete the parts below to perform a hypothesis test to see if there is enough evidence, at the 0.10 level of significance, to reject the claim that the proportion, p, of all students who will find a match their first time using the site is 39%. (a) State the null hypothesis H, and the alternative hypothesis H₁ that you would use for the test. Ho: H₁:0 р 0<0 0<0 □□ 0=0 (b) For your hypothesis test, you will use a Z-test.

In the past, 74% of the tourists who visited Chattanooga went to see Rock City. The management of Rock City recently undertook an extensive promotional campaign. They are interested in determining whether the promotional campaign actually increased the proportion of tourists visiting Rock City. Which of the following is the correct set of hypotheses? Ho: p 0.74 Ha: ps 0.74 O Ho: Ps 0.74 Ha: p > 0.74
The local Hannaford is tracking mask compliance in their stores. In mid-March they found that only 40% of customers were wearing masks. They want to know if that percentage increased with the government mandates in place. Select the correct symbols to write the alternate hypothesis for this hypothesis test. Ha:
Find the P-value for the indicated hypothesis test.In a sample of 47 adults selected randomly from Vancouver, it is found that 9 of them have been exposed to the flu. Find the P-value for a test of the claim that the proportion of all adults in Vancouver that have been exposed to this strain of the flu is more than 8%.

In order to assess the effects of exercise on reducing cholesterol, a researcher took a random sample of fifty people from a local gym who exercised regularly and another random sample of fifty people from the surrounding community who did not exercise regularly. They all reported to a clinic to have their cholesterol measured. The technician measuring the cholesterol was not aware of whether or not subjects exercised regularly.
