An advertisement claims that Fasto Stomach Calm will provide relief from indigestion in less than 10 minutes. For a test of the claim, 25 individuals were given the product, and the average time was 9.25 minutes. From the past studies, the standard deviation is known to be 2 minutes. Can one conclude that the claim is justified? Find the P-value, and let a = 0.05. Assume that the variable is approximately normally distributed. Construct a corresponding confidence interval for the population parameter.O, X+Z.95 VI
