Answer:
a) the value of 135 because it is not greater than 136.5
Step-by-step explanation:
Given that
n = sample size =85
Mean = 146
std dev =34
Std error of sample = 34/sqrt 85
= 3.6878
99% z critical value = 2.58
Margin of error = ±9.515
Confidence interval lower bound = 146-9.515 = 136.485
Upper bound = 146+9.515 =155.515
Hence we find that 135 is less than lower bound, hence 135 does not lie within 99% confidence interval
a) the value of 135 because it is not greater than 136.5

If you have to divide 12 into 4 separate groups they would all be 3
3+3+3+3=12 1/4+ 1/4+ 1/4+ 1/4= 1 hope that helps
