How to calculate P(Xbar > 13.33).

Before finding this probability first we have to know the mean and standard deviation of the variable.

For finding this probability we have to find z score.

z score is

n: Sample size

: Mean

: Standard deviation.

Find the value of the z score.

After finding the value of the z, see probability in the z table we will get answer.

Use this formula to find a confidence interval which is xbar +/-E where E is = zc* s / sqrt n On the first one we will have a 95% confidence interval with z=1.96 and n=100 Pick a number for xbar between 60-100. Pick a number for s between 4-8. Find the confidence interval given xbar +/- E Note to find the square root of n use n^.5 where you are raising to the .5 or 1/2 power which is...
