A normal distribution has µ = 60 and sigma = 8. What is the probability of obtaining a sample mean greater the x = 62 for a sample of n = 24 scores?

Homework Answers

Answer #1

The probability of obtaining a sample mean greater the x = 62 for a sample of n = 24 scores is 0.1103=11.03%

The R-code is to compute probability

1-round(pnorm(1.2247),4)

 [1] 0.1103
