What is the shape of the samplingdistribution of x? The amount that households pay serviceproviders for access to the Internet variesquite a bit, but the mean monthly fee is$48 and the standard deviation is $20.The distribution is not normal: Manyhouseholds pay a base rate for low-speedaccess, but some pay much more forfaster connections. A sample survey askSan SRS of 500 households with Internetacess how much they pay per month. Letx be the mean amount paid by themembers of the sample.

A researcher wants to check the claim that a certain species of reptile spend an average of 18.2 months in quaratine before being transported to another facility. She takes a random sample of 25 such cases from files and finds that ī = 18.9 months and the sample standard deviation, s = 3.6 months. Test the claim at the 0.1 significance level. What are the correct hypotheses? (Select the correct symbols and use decimal values not percentages.) Ho: Select an answer v months H: Select an answer v months Original claim = Select an answer v Based on the hypotheses, find the following: Test Statistic = |(Round to three decimal places and show work in the "show work" box below.) p-value = (Round to four decimal places and show work in the "show work" box below.)
