The average height of an adult male is 60.45" with a standard deviation of 1.02". Calculate an interval that is symmetric around the mean such that it contains approximately 95% of heights. Assume that height has a normal distribution. Question 8 options: 1) (59.43, 61.47) 2) (58.41, 62.49) 3) (61.47, 59.43) 4) (62.49, 58.41) 5) (60.45, 1.02)

Dr Z decided to investigate the productivity of her plutonium mines. The standard deviation for the output is known (fat hint: use z-tables) and is 5 tons a day. The average output in a sample of a 400 mines was 66 tons. At 95% confidence level, what is the lower border of the confidence interval? (Two decimals) Chint: don't get confused here: you have been always asked for both, the lower and the upper values for the confidence interval but...
