Aconsumer products company is formulating a new shampoo and is interested in foam height (in millimeters). foam height is approximately normally distributed and has a standard deviation of 20 millimeters. the company wishes to test h0: μ⁢=equals 175 mm versus h1: μ ⁢> 175 mm, using the results of n=4 samples. calculate the p-value if the observed statistic is round your answer to four decimal places (e. g. 98.7654).

Use the given degree of confidence and sample data to construct a confidence interval for the population mean mu . assume that the population has a normal distribution. a laboratory tested twelve chicken eggs and found that the mean amount of cholesterol was 185 milligrams with sequals 17.6 milligrams. a confidence interval of 173.8 mgless than muless than 196.2 mg is constructed for the true mean cholesterol content of all such eggs. it was assumed that the population has a normal distribution. what confidence level does this interval represent?
