2) The incubation time for Rhode Island Red chicks is normally distributed with a mean of 21 ( days and standard deviation of approximately 1 day (based on information from The Merck Veterinary Manual). If 1000 eggs are being incubated, how many chicks do we expect will hatch in each of the following ranges of days. Hint: How many standard deviations away from the mean are each of the numbers of days? a) in 19 to 23 days? b) in 20 to 22 days? c) in 21 days or fewer? d) in 18 to 24 days (Assume all eggs eventually hatch) ercentages for ANY the standard normal tables εe.I - = s brun 0= s nuswis (8 80.5% bas 0.1-snoowell (@ popolatie Warspro Note: In this problem, let us agree to think of a single days or a succession of days as a continuous interval of time. 20.0-s bra Ber- = snows8 (11
