Our favorite deity has informed us that the true mean of x is 0 and its true standard deviation is 5.
How small would x have to be such that 97.5% of X's are larger? (Show work)
Homework Answers
Mean(x) = 0
standard deviation =s(x) = 5
Find x such that, P[X > x ] = 97.5% = 0.975
Also, we know that
P[ Z > -1.96 ] = 0.975
P[X > -9.8 ] = 97.5% = 0.975

The serum cholesterol levels for 20-24 year old males in the US has mean 180 mg/100ml and standard deviation σ = 46 mg/100ml. We are interested in the mean cholesterol level of the larger population of 20-74 old males, say µ. Suppose, we have a random sample of size 25 from the larger population. We want to test the following hypotheses at significance level α = 0.01: H0 : µ = 180, HA : µ > 180 a) What is...

Let x represent the dollar amount spent on supermarket impulse buying in a 10-minute (unplanned) shopping interval. Based on a certain article, the mean of the x distribution is about $30 and the estimated standard deviation is about $5. (a) Consider a random sample of n = 40 customers, each of whom has 10 minutes of unplanned shopping time in a supermarket. From the central limit theorem, what can you say about the probability distribution of x, the average amount...
