t, in a sample ofn= 161 selected from a right-skowed population, X= 67 and S-19, would you use the t test to test the nul hypothesis H, 58?Choose the correct answer belowOA No, you would not use the t test because the sample size is at loast 30 and the population is right-skewed.OB. Yos, you would use the t test because the sample size is less than 30 and this population size allows for the Central Limit Theorem to take effect.OC. Yes, you would use the t test because the sample size is at least 30 and this population size allows for the Central Limit Theorem to take effect.OD. No, you would not use the t test because the sample size is less than 30 and the population is right-skowod.

A recent study showed that in a random sample of 100 people, 30% had visited Worlds of Fun. In another random sample of 150 people 24% had visited Knott’s Berry Farm. At ∝ = 0.05 are the proportions of people who visited each park different? The samples were independent. In a two sample hypothesis test the p-value was 0.2917. In this test your decision would be to reject the null hypothesis fail to reject the null hypothesis accept the alternate hypothesis as true none of the above
Dr J claims that 40 percent of his college algebra class will drop his course by midter,. To test the claim, he selcted 45 names at random and discovered that 20 of them had already dropped long before midterm. The test statistic value for his hypothesis test is a. 8.3333b. 0.3704c. 0.6086d. 0.6847

A batch of cookies is sent out for sale if more than 95% pass a yum test. Rather than test every cookie in the batch, they only test sample n=250 from each batch. In batch #42, of the 250 cookie tests, 245 of them passed the yum test. Using this data, test the null hypothesis that H0: p=.95 vs Ha: p>.95 at the a=.1 level. What is the p-value of this test, and what is your conclusion?
In a sample of 49 men, 38 said that they had less leisure time today than they had 10 years ago. In a sample of 49 women, 30 women said that they had less leisure time today than they had 10 years ago. At α=0.01, is there a difference in the proportions?Use p1 for the proportion of men with less leisure time. State the hypotheses and identify the claim with the correct hypothesis. H0 : p1=p2 ▼not claim H1 : p1≠p2 ▼claim This hypothesis test is a ▼two-tailed test. Find the critical value(s). Round the answer(s) to two decimal places. If there is more than one critical value, separate them with commas. Critical value(s):_______________
A study found that 1 out of 200 adult males have green eyes. If a random sample of 400 adult males is obtained, is the sampling of the sample proportion of males that have green eyes approximately normal? A. Yes, the sample size is greater than 10% of the population. B. Yes, the sample was randomly selected C. No, because np < 10 D. No, because nq < 10
DO The one-sample -statistic for a test of Ho: 4 = 42 versus H, : I < 42 based on n = 15 observations has the value § 1 = - 1.343, where Ho and H are the null and alternative hypotheses, respectively. The sample size is denoted by n. cmillan Use this 1-table to determine which two P-values bracket the P-value of the test. Report your answers in decimal form as © Ma listed in the t-table.
A survey of heads of households showed the percentage of those who asked for a raise and the percentage of those who asked for a raise and the percentage who got one. Accordig to the survey, of the men interviwed 16% asked for a raise, and of those men who asked for a raise, 65% recieved the raise. If a man is selected at random from the survey population of women, find the following probabilites. (To three decimal places) P(man asked for a raise) P(man recieved raise, given he asked for one) P(man asked for raise and recieved raise)
In the tt-test of significance for the hypotheses H0:μ=11 and Ha:μ<11, the value of the test statistic was found to be t = 1.205 using a sample of size 18. Estimate the upper bound for the P-value associated with this test. That is, fill in the blank P <P< _____. Please show work!
