i need help i don't know how to do this problems

i1} HIEHLIGHI the intervals containing p = 69 inches on your printouts. {2) Calculate the width of each interval {i.e._ subtract the lower limit from the upper lirnitj and type all these widths {do not round] next to the intervals W This would be 2D calculations per printout {total of 4G widths]. Fill-in the table below with requested information about the printouts. 3. Questions a-rdin- the .rintouts @ a. How many of the 2D intervals do HIE contain [1 = 59 inches? -_ b. How manyr of the 2C! intervals M p = 69 inches? -_ -- p = 69 inches? d. Do all the intervals have the same or approximately the -- 4. a. Based on the condence level used in this task, what percentage of the intervals did you exgct to contain u? ANS: b. 1!.!.!|:|1'Hettplain in detail: see rst page of this lab and overview video on the lab) Compare the widths of the z-intenrals with the t-intenrals. a. Which kind of interval. torz, seems to be wider? ANS: I1 Evan reason. other than sample size. that explains your obsewation in part 5a? (HINT: Look at the class handout on the t distribution and the lap overview on the first page of this lab. Need to identify a feature other than sample size.)
