Draw a box-and-whisker plot for the set of data. 27, 35, 44, 51, 52, 54, 56, 69, 69, 79, 80, 100, 100
a.
A box-and-whisker plot. The number line goes from 0 to 100. The whiskers range from 27 to 80, and the box ranges from 47 to 80. A line divides the box at 56.
b.
A box-and-whisker plot. The number line goes from 0 to 100. The whiskers range from 27 to 100, and the box ranges from 47 to 80. A line divides the box at 56.
c.
A box-and-whisker plot. The number line goes from 0 to 100. The whiskers range from 1 to 100, and the box ranges from 47 to 80. A line divides the box at 56.
d.
A box-and-whisker plot. The number line goes from 0 to 100. The whiskers range from 23 to 100, and the box ranges from 47 to 80. A line divides the box at 56.

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
