SE = 0.33
Varience = 7.6 , standard deviation = sigma = sqrt(7.6) = 2.76
Standard error = SE = sigma / sqrt ( n )
0.33 = 2.76 / sqrt (n)
Sqrt ( n ) = 2.76 / 0.33
n = ( 2.76 / 0.33 ) 2 = 69.79 = 70

Consider a population having a standard deviation equal to 9.96. We wish to estimate the mean of this population. (a) How large a random sample is needed to construct a 95% confidence interval for the mean of this population with a margin of error equal to 1? (Round your answer to the next whole number.) The random sample is units. (b) Suppose that we now take a random sample of the size we have determined in part a. If we...
