I’m taking a probability and a statistics class. Please get this correct so I can study.
A local bookstore arranges book counter in different schools around the year. The CEO says that, compare to last year, the number of orders received in school has been dropped this year. The table below shows the number of orders received in a random sample of 14 schools in this year and last year. School 1 3 4 6. 8. 9. 10 11 12 13 14 This year 85 35 96 45 33 52 67 77 45 67 43 76 80 65 Last year 92 38 93 81 42 50 61 89 56 63 49 65 92 81 Test, at 5% level of significance, is there sufficient evidence to conclude that the CEO's statement is correct. (The test report must include (i) null hypothesis and alternative hypothesis, (ii) rejection region, (iii) calculation of test statistics, and (iv) conclusion.)
Use the data in the following table, which lists drive-thru order accuracy at popular fast food chains. Assume that orders are randomly selected from those included in the table.

ASK YOUR TEACHER Nationally, about 11% of the total U.S. wheat crop is destroyed each year by hail.t An insurance company is studying wheat hail damage claims in a county in Colorado. A random sample of 16 claims in the county reported the percentage of their wheat lost to hail. 14 7 10 11 12 19 14 11 9 8 23 19 13 7 10 7 The sample mean is x = 12.1%. Let x be a random variable that represents the percentage of wheat crop in that county lost to hail. Assume that x has a normal distribution and a = 5.0%. Do these data indicate that the percentage of wheat crop lost to hail in that county is different (either way) from the national mean of 11%? Use a = 0.01. (a) What is the level of significance? State the null and alternate hypotheses. Will you use a left-tailed, right-tailed, or two-tailed test? O Ho: H = 11%; H,: µ 11%; right-tailed O Ho: H + 11%; H,: u = 11%; two-tailed O Ho: H = 11%; H,: u + 11%; two-tailed (b) What sampling distribution will you use? Explain the rationale for your…
