According to Example 12, a normal distribution with mean 115 and standard deviation 22 hun- dredths of an inch describes variation in female salmon growth in fresh water.
(a) If a newly caught female salmon has growth 108, what is the corresponding standard- ized score?
(b) If a standardized score is -.8, what is the growth measurement?
(c) Find the interval of standardized scores corresponding to the growth measurements 105 to 128.
(d) Find the interval of growth measurements corresponding to the standardized scores of -1.5 to 1.5.
