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

the one that has a slope of 1/2 and is positive.

step-by-step explanation: 2 buckets 1 trip ; 4 buckets 2 trips and so on.
