An experiment consists of drawing a marble out of a bag, observing the color, and then placing it back in the bag. Suppose the
experiment is repeated 75 times, with the following results:
red 38
blue 23
green 11
yellow 3
Suppose it is known that there is a total of 300 marbles in the bag. Estimate the number of each color of marble.
a red 152; blue 92; green 44; yellow 12
C. red 150; blue 85; green 40; yellow 10
red 100; blue 95; green 60; yellow 15
d. red 130; blue 91; green 53; yellow 19

Acell phone company offers two plans to its subscribers. at the time new subscribers sign up, they are asked to provide some demographic information. the mean yearly income for a sample of 40 subscribers to plan a is $45,000 with a standard deviation of $9,200. for a sample of 25 subscribers to plan b, the mean income is $64,300 with a standard deviation of $7,100. at the 0.025 significance level, is it reasonable to conclude the mean income of those selecting plan b is larger? assume unequal population standard deviations. hint: for the calculations, assume the plan a as the first sample. what is the decision rule? (negative amount should be indicated by a minus sign. round your answer to 3 decimal places.) compute the value of the test statistic. (negative amount should be indicated by a minus sign. round your answer to 2 decimal places.) what is your decision regarding h0 ? reject h0 fail to reject h0 compute the p-value. less than 0.01 between 0.01 and 0.025 between 0.025 and 0.05 between 0.05 and 0.10 greater than 0.10
