For a particular English course, students are required to read two out of three books on the course assignment list. The number of pages for each book is as follows:  400,  388, and 242. Assume that two of the books are selected at random with replacement. Here is a table summarizing the probability distribution of the sample mean:   sample mean Probability     242 1/9       315  2/9     321  2/9     388  1/9     394  [BLANK-1]     400  1/9    BLANK 1:  Fill in the missing probability in the table above.  Use simplified fractions. Use the ” / ” symbol to separate the numerator and denominator of the fraction. BLANK 2:  Find the population mean:   µ   =   [BLANK-2]    round to 1 decimal place BLANK 3:  Find the mean of the sample means:  [BLANK-3]     round to 1 decimal place BLANK 4:  Do the sample means TARGET the population mean? Write YES or NO in the blank:   [BLANK-4] BLANK 5: Determine whether mean is considered a biased or an unbiased estimator.                       MEAN is considered a(n) [BLANK-5].
