Task8. [5pts] There is an inscription on the matchboxes: 48 matches on average. A random sample of 20 boxes was taken from the morning delivery and it was calculated that the average number of matches in a box is 47.5 pcs and the standard deviation in this sample is 3 pm. We assume that the distribution of the number of matches in the boxes is normal N (m, a). At the a = 0.01 signicance level, determine if the inscription on the box is consistent with reality. Also set a critical signicance level. (Answer: 01m: = 0.24) Tast. [Sptsl Formulate a task analogous to task 8 and present its solution :) The list of individual data should contain at least 20 elements. Taskl. [511133] Formulate a task analogous to task 4 and present its solution :)
