The average waist size of the population is 85 cm, and the standard deviation is 15 cm. then A sample mean waist size of at least 86.3 cm has a 0.931 probability of occurring.

We can use the Z-score formula to find the probability.

Z = (86.3 - 85) / (15 / sqrt(277))

Z = 0.2 / 0.106

Z = 1.89

The probability of a sample mean waist size of at least 86.3 cm is 0.931.
