Consider a slide. The top of the slide is 7 ft from the ground. The base of the slide is 10 ft from the ladder. What is the slope of the slide? If you were at the base of the slide, and moved 2 feet closer to the slide, how high is the slide at this point? How high off the ground would the slide be if you moved the slide base 2 ft towards where the ladder was? How far from the ladder would the base of the slide need to be placed if you wanted the slide to have a slope of 1/2?

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
