Question text According to the most recent census, the average total yearly expenses of households in Wake County is $45,900. It is also known that the distribution of household expense in Wake County is strongly skewed to the right with a standard deviation of $8,370. A researcher is going to randomly select a sample of 7 households from Wake County. Which of the following is true? Select all that apply. Select one or more: a. The sampling distribution of the...

Question 12 (1 point) Consumers Energy states that the average electric bill across the state is $108.57. You want to test the claim that the average bill amount is actually greater than $108.57. The hypotheses for this situation are as follows: Null Hypothesis: μ ≤ 108.57, Alternative Hypothesis: μ > 108.57. You complete a randomized survey throughout the state and perform a one-sample hypothesis test for the mean, which results in a p-value of 0.6273. What is the appropriate conclusion?...

The average number of hours that Canadians spend on the internet at home has been 100...
The average number of hours that Canadians spend on the internet at home has been 100 hours per month for several years. In early March of 2020, as more people were starting to work and study at home, a random sample of 25 households found a mean of 104 hours with a sample standard deviation of 10 hours. The population standard deviation is unknown. Assume that hours spent on the internet are approximately normally distributed. Is there enough evidence to...
