A life insurance representative believes that the mean age of people who buy their first life insurance plan is of 15 customers who have just purchased their first life insurance. Their ages are: 42 43 28 34 30 36 25 29 32 33 27 There is not enough evidence to say the data are nonnormal. We want to conclude at the 1% significance level what is rejection region

don't know what that says sorry i can't you

step-by-step explanation:

idk what it says

i will u if u answer my question in math

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.
