Step-by-step explanation:
given that certain tubes manufactured by a company have a mean lifetime of 800 hours and a standard deviation of 60 hours.
Sample size n =16
Std error of sample mean =
x bar follows N(800, 15)
the probability that a random sample of 16 tubes taken from the group will have a mean lifetime
(a) between 790 and 810 hours,
=
(b) less than 785 hours
, (c) more than 820 hours,
(d) between 770 and 830 hours

A Venn diagram is used to present the relationship between sets in a logical form
Please find attached the completed Venn diagrams for the questions with the contents outlined as follows;
1. The set of whole numbers 1 to 15 = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15}
Set A = All even numbers in this set
Set A = {2, 4, 6, 8, 10, 12}
2. The set of whole numbers from 1 to 20
Set C = All even numbers = {2, 4, 6, 8, 10, 12, 14, 16, 18, 20}
Set D = All multiples of 4 = {4, 8, 12, 16, 20}
3. The set of all whole numbers from 1 to 20
Set E = {2, 4, 6, 7, 9, 10}
Se F = {3, 4, 5, 9, 10, 13, 15, 16, 19,20}
