Internet Service ProvidersThe amount that households pay service providers for access to the Internet variesquite a bit, but the mean monthly fee is $50 and the standard deviation is $20. Thedistribution is not Normal: many households pay a low rate as part of a bundle withphone or television service, but some pay much more for Internet only or for fasterconnections.A sample survey asks an SRS of 50 households with Internet access how much theypay. Let x be the mean amount paid.1. Explain why you can't determine the probability that the amount a randomlyselected 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 householdsexceeds $55.

For the distribution of internet service fees (which is stated to be not normal), it is given that:…
