Use the t-distribution to find a confidence interval for a difference in means M - U2 given the relevant sample results. Give the best estimate for ui - U2, the margin of error, and the confidence interval. Assume the results come from random samples from populations that are approximately normally distributed. = 30 and X2 = 64.5, A 95% confidence interval for Mi - uz using the sample results īj = 82.3, si = 10.8, n S2 = 6.9, n2...

please help me to solve part b
The recommendations of respected wine critics have a substantial effect on the price of wine. Vintages that earn higher ratings command higher prices and spark surges in demand. These data are a random sample of ratings of wines selected from an online Web site from the 2000 and 2001 vintages. Complete parts (a) through (d). Click the icon to view the table of wine rating, price, and vintage. (a) Do the ratings meet...

In this exercise we will compute the probability that in a random graph with vertex set V we have that v and v2 have an edge between them or have an edge to a common vertex (i.e, have a common neighbour) (If you are troubled by my use of the term random we choose a graph on n vertices uniformly at random from the set...
