The mean number of eggs per person eaten in the United States is 252 and the standard deviation is 68. Do college students eat more than the average? The 45 college students surveyed averaged 281 eggs per person. What can be concluded at the 0.05 level of significance? H0: = 252 Ha: _____________ 252 Test statistic: __________    p-Value =__________                    Reject/Fail to reject H0?______________         Conclusion: There is____________   evidence to make the conclusion that the population mean number of eggs consumed college students per year is more than 252 eggs per student per year. p-Value Interpretation: If the mean number of eggs consumed per year for college students is equal to_________  and if another study was done with a new randomly selected group of 45 college students, then there is a ____________ percent chance that the average number of eggs consumed per year for this new sample would be greater than_____________        . Level of significance…

Using Symmetry and the Empirical Rule A standardized test is approximately normally distributed with a mean score of 7272 and a standard deviation of 55. Use the symmetry of the normal curve and apply the Empirical rule to answer the questions. Make a sketch of the curve to help you determine the areas.Note: You must use the Empirical Rule values 68%68%, 95%95%, and 99.7%99.7% in your computations. The computer calculator will not give you the correct answer. What percent of students scored greater than 7272?____ % What percent of students scored between 7272 and 7777?_______ % What percent of students scored between 6767 and 7777? ______% What percent of students scored between 5757 and 6262? _____%
