Now it's time to tackle the original question.
Going from point A to point B, the cheetah traveled at an average rate of 70 mph. Returning to
point A, the cheetah traveled at an average rate of 40 mph
Can we say that this cheetah's average rate was 55 mph?
a. The average rate for the trip is equal to the total distance traveled divided by the total
time traveled. The following equations represent the distance traveled on each leg of the
trip

The random variable x represents the number of phone calls an author receives in a day, and it has a poisson distribution with a mean of 8.7 calls. what are the possible values of x

What is the value of the expression i 0 × i 1 × i 2 × i 3 × i 4? 1 –1 i –i

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
