Document Summary

= 115, the distribution is approximately normal with mean. 15. 1: if deviation fairly close to the middle. If surprising, but 125. 8 is less likely, and it therefore provides some evidence that. = 115, observing a value similar to 118. 6 would not be too. = 6. (b) the actual result lies out toward the high tail of the curve, while 118. 6 is. = 10. 1, then the sampling distribution of x is approximately normal with mean. = 0. 041. (b) the plot provided shows sampling distribution. = 10. 1 and standard deviation x = 9. 95. On the plot are the two indicated values of x = 9. 95 that a value of would be very unusual (more than 3 standard deviations away from 10. 1). 9. 95 would provide reason to doubt that x = 10. 09 would not be unusual if, in fact, = 10. 1, while a value of x = 10. 09 would not. = 10. 1, while x = 10. 09 and n x =
