You are interested in finding a 98% confidence interval for the average number of days of classthat college students miss each year. The data below show the number of missed days for 14randomly selected college students. Round your mean and standard deviation to three decimalplaces when doing these calculations.2 4 11 | 5 2 | 7| 3| 12 | 3 | 11 || 9|2| 11 | 5Download CSV| distribution.b. With 98% confidence the population mean number of days of class that college students missdays. Round to two decimal places.a. To compute the confidence interval use aandis betweenc. If many groups of 14 randomly selected non-residential college students are surveyed, then adifferent confidence interval would be produced from each group. Aboutpercent ofthese confidence intervals will contain the true population mean number of missed class daysand aboutpercent will not contain the true population mean number of missed classdays.

The distribution of heights in a population of women is approximately normal. Sixteen percent of the women have heights less than 62 inches. About 97.5% of the women have heights less than 71 inches. Use the empirical rule to estimate the mean and standard deviation of the heights in this population. Mean: K inches Standard Deviation: inches
A researcher wishes to test the effects of excerise on the ability to complete a basic skills test. He designs a pre-test and post-test to give to each participant. You believe that there was a difference in the scores. You believe the population of the differences is normally distributed, but you do not know the standard deviation. When calculating difference use Post-test minus Pre-test. pre-test post-test 63 71 97 94 66 66 41 32 96 97 41 45 79 81 98 106 76 70 63 70 42 47 86 94 Which of the following are the correct hypotheses?

Facebook Friends Many people believe that the average number of Facebook friends is 140. The population standard deviation is 39.6. A random sample of 30 high school students in a particular county revealed that the average number of Facebook friends was 147. At a=0.10, is there sufficient evidence to conclude that the mean number of friends is greater than 140? Use the P-value method. Use a graphing calculator. Part 1 of 4 (a) State the hypotheses and identify the claim. Ho: 140 not claim H₁>140 claim This hypothesis test is a one-tailed Part: 1/4 Part 2 of 4 test. (b) Find the P-value.

esc Introduction A chain of restaurants has historically had a mean wait time of 9 minutes for its customers. Recently, the restaurant added several very popular dishes back to their menu. Due to this, the manager suspects the wait time, μ, has increased. He takes a random sample of 44 customers. The mean wait time for the sample is 9.6 minutes. Assume the population standard deviation for the wait times is known to be 3.3 minutes. Can the manager conclude that the mean wait time is now greater than 9 minutes? Perform a hypothesis test, using the 0.05 level of significance. (a) State the null hypothesis Ho and the alternative hypothesis H₁. Ho: O H₁:0 (b) Perform a Z-test and find the p-value.

A highschool teacher is interested in examining the math performance of one particular child, Mike, he has observed over several years. The highschool teacher has the mean and standard deviation for each year's maths test along with Mike's score on each test. Year Mean SD Mike's score 2018 90.5 5.1 96 2019 88.7 8.8 95 2020 69.5 3.4 78 Calculate the appropriate statistic to evaluate in which year Mike did his best in the math test relative to the other children tested over the years. To answer this question, we would need to compute a Q1. ABCD for each year, which would be Q2. ABCD for 2018, Q3. ABCD for 2019, and Q4. ABCD for 2020. This would mean that Mike's best math performance was in Q5. ABCD relative to the other children tested over the three years. In that year, he performed better than Q6. ABCD of the other children. Possible answers for Q4:A) -2.50B) -1.67C) 1.67D) 2.50 Possible answers for Q5:A) 2018B) 2019C) 2020D) Cannot tell…
