The compressive strength of concrete is normally distributed with u= 2200 psi and o? 50 psi. Find the probability that a random sample of n 10 specimens will have a sample mean diameter that falls in the interval from 2198 psi to 2203 psi. If we increase our sample size, would this increase the probability that our sample mean will be between the interval? Explain and include your solutions. O a. Probability is about 72%. Increasing the sample size will increase this probability b. NONE O. Probability is about 12%. Increasing the sample size will increase this probability O d. Probability is about 72%. Increasing the sample size will decrease the probability

Transcribed Image Text:The compressive strength of concrete is normally distributed with u= 2200 psi and o? 50 psi. Find
the probability that a random sample ofn 10 specimens will have a sample mean diameter that falls
in the interval from 2198 psi to 2203 psi. If we increase our sample size, would this increase the
probability that our sample mean will be between the interval? Explain and include your solutions.
O a. Probability is about 72%. Increasing the sample size will increase this probability
O b. NONE
O. Probability is about 12%. Increasing the sample size will increase this probability
O d. Probability is about 72%. Increasing the sample size will decrease the probability
