Astudy of 40 people found that they could do on the average15 pull ups with a standard deviation of 0.6. find the 99% confidence interval for the mean of the population.

[14.75, 15.24]

Step-by-step explanation:

Sample mean = 15  

Sample standard deviation = 0.6  

Number of samples = 40

The t value for 99% confidence interval (t - critical value table) is 2.58

Now to find the 99% confidence interval for the mean of the population, we will do the following:

and

[14.75, 15.24]

a

explanation:

$4

step-by-step explanation:

$30×5=$150

$150 minus $130=$20

$20÷5=$4.
