In a genetics lab, 65 fruit flies were sampled for the amount of
time it takes for them to mature into fully grown adult flies. The
test showed an average time of 18.5 days for this to happen. If the
data follows a normal distribution with a standard deviation of 59
hours, find the 95% confidence interval for the true mean of the
dataset. (Hint: Make sure that the unit of measurements are the
same for the given parameters)
A) (18.195 days, 18.805 days)
B) (17.902 days, 19.098 days)
C) (63.88 days, 66.12 days)
D) (17.998 days, 19.002 days)
