Jenny has two ways to get from her home in Norco to her office in Los Angeles. One is on the San Bernardino Freeway and the other on the Pomona Freeway. Recently, she added a lane to the San Bernardino Freeway. Jenny wants to determine if it is now faster to take the San Bernardino Freeway than the Pomona Freeway. She selected a random sample offiftfettheir drives on the San Bernardino Freeway and a random sample offiftefenis trips on the Pomona Freeway. The two samples were chosen separately, so the selection of the San Bernardino Freeway trips did not affect the selection of the Pomona Freeway trips. Jenny recorded the runs (in minutes) on each of the two samples. The following table provides the data, the sample means, and the sample standard deviations.

Internet Service Providers The amount that households pay service providers for access to the Internet varies quite a bit, but the mean monthly fee is $50 and the standard deviation is $20. The distribution is not Normal: many households pay a low rate as part of a bundle with phone or television service, but some pay much more for Internet only or for faster connections. A sample survey asks an SRS of 50 households with Internet access how much they pay. Let x be the mean amount paid. 1. Explain why you can't determine the probability that the amount a randomly selected household pays for access to the Internet exceeds $55. 2. What are the mean and standard deviation of the sampling distribution of x ? 3. What is the shape of the sampling distribution of x ? Justify your answer. 4. Find the probability that the average fee paid by the sample of households exceeds $55.
