Solution :
Given that ,
n = 6
df = n - 2 = 6 - 2 = 4
= 0.025
t 0.025,4 = 2.776
Critical value = 2.776

Let x be a random variable that represents the weights in kilograms (kg) of healthy adult female deer (does) in December in a national park. Then x has a distribution that is approximately normal with mean y = 57.0 kg and standard deviation o = 7.9 kg. Suppose a doe that weighs less than 58 kg is considered undernourished. (a) What is the probability that a single doe captured (weighed and released) at random in December is undernourished? (Round your...
A.) Let x be a random variable representing dividend yield of bank stocks. We may assume that x has a normal distribution with ? = 2.0%.
