Suppose the weights of the Boxers at this club are Normally distributed with a mean of 166 pounds and a standard deviation of 5.3 pounds. What is the probability that the mean weight of a random sample of 20 boxers is more than 167 pounds?

0.1994 is the required probability.      

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 166 pounds

Standard Deviation, σ = 5.3 pounds

Sample size, n = 20

We are given that the distribution of weights is a bell shaped distribution that is a normal distribution.

Formula:

Standard error due to sampling =

P(sample of 20 boxers is more than 167 pounds)

Calculation the value from standard normal z table, we have,  

0.1994 is the probability that the mean weight of a random sample of 20 boxers is more than 167 pounds

hope this !

you should talk someone who owns the website about it. you did not deserve to have all that hard work and time taken away. id watch videos of little puppies to cool you down, and maybe some nacho cheese doritos.
