In a recent survey of high school students, it was found that the average amount of money spent on entertainment each week was normally distributed with a mean of $\$52.30$ and a standard deviation of \$18.23. Assuming these values are representative of all high school students, what is the probability that for a sample of 25 , the average amount spent by each student exceeds $\$60$ ? 0.3372 0.0174 0.1628 0.4826 QUESTION 16 If all possible namples of size $n$ are drawn from a population, the probability distribution of the sample means is called the: standard error of the sample mean. expected value of the sample mean. sampling distribution of sample means. normal distribution. QUESTION 17 The variance of the sampling distribution of the sample mean is equal to the variance of the population mean divided by the square root of the sample size. True Falso
