Estimating the Standard Deviation: Veterinary Science How much should a healthy kitten weigh? A healthy 10-week-old (domestic) kitten should weigh an average of m = 24.5 ounces with a (95% of data) range from 14 to 35 ounces. (See reference in Problem 33.) Let x be a random variable that represents the weight (in ounces) of a healthy 10-week-old kitten. Assume that x has a distribu- tion that is approximately normal.
(a)Â Â Â Â Estimate the standard deviation of the x distribution. Hint: See Problem 31.
(b)Â Â Â What is the probability that a healthy 10-week-old kitten will weigh less than 14 ounces?

(c)Â Â Â Â
What is the probability that a healthy 10-week-old kitten will weigh more than 33 ounces?
(d)   What is the probability that a healthy 10-week-old kitten will  weigh between 14 and 33 ounces?
(e)    Inverse Normal Distribution A kitten whose weight is in the bottom  10% of the probability distribution of weights is called undernourished. What is the cutoff point for the weight of an undernourished kitten?
