Asimple random sample has a sample size of n=65. given the population is normally distributed, find the critical value t_a/2 corresponding to a 99% confidence level.

2.6549

Step-by-step explanation:

Since the sample size n=65, the degrees of freedom is n-1=65-1=64

The critical value=

Using the t-table and selecting df=64 and since it’s a 2 tail the corresponding t-score is 2.6549

Therefore, the critical value is 2.6549

i belive those are the ones that are under 90 degreese.

the 1st digit is in the 100s n its 1

step-by-step explanation:

3,589÷18 = 199.389

so the first digit of the quotient is in the 100s n its 1
