In this problem, assume that the distribution of differences is approximately normal. Note: For degrees of freedom d.f. not in the Student's t table, use the closest d.f. that is smaller. In some situations, this choice of d.f. may increase the P-value by a small amount and therefore produce a slightly more "conservative" answer. A survey of houses and traditional hogans was made in a number of different regions of the modern Navajo Indian Reservation. The following table is the result of a random sample of eight regions on the Navajo Reservation.   I need help with (c), sketching and (d) and (e)

In this problem, assume that the distribution of differences is approximately normal. Note: For degrees of freedom d.s. not in the Student's t table, use the closest d.f. that is smaller. In some situations, this choice of d.r. may increase the Pvalue by a small amount and therefore produce a slightly more "conservative" answer. Are America's top chief executive officers (CEOS) really worth all that money? One way to answer this question is to look at row B, the annual company percentage increase in revenue, versus row A, the CEO's annual percentage salary increase in that same company. Suppose a random sample of companies yielded the following data: B Percent increase 24 25 25 18 6 for company 21 37 4 A: Percent increase 23 for CEO 22 14 -4 19 15 30 A USE SALT Do these data indicate that the population mean percentage increase in corporate revenue (row B) is different from the population mean percentage increase in CEO salary? Use a 5% level of significance. (Let d - B - A.) (a) What…

Which of the following is NOT true about statistical graphs? Choose the correct answer below. O A. They can be used to identify extreme data values. O B. Similar graphs can be constructed in order to compare data sets. O C. They utilize areas or volumes for data that are one-dimensional in nature. O D. They can be used to consider the overall shape of the distribution. ...

Which of these choices below would be the best choice to address such errors of measurement?  a. Broaden the range (i.e., spread) between the control limits. b. Reduce the range between the specification limits. c. Reduce the spread between the control limits. d. Broaden the range between the specification limits. Choices c, and d are true (i.e., reduce the spread between the control limits and broaden the range between the specification limits).
