We want to determine if the average age of all the students in the MSBA program is significantly different from 24 years. We select a random sample of 20 students and determined the mean age for this group of students is 24.7 years. Let's assume the distribution of the population of ages follows normal distribution and the population standard deviation is 1.8 years. According to the above information, answer the following two questions.
Calculate the test statistic. Keep 2 decimals
At a = 0.05, what is your conclusion? the average age is significantly different from 24 years the average age is greater than 24 years old the average age is not significantly different from 24 years no conclusion can be made according to the above information
