Using the confidence interval from part a, can you reject the null hypothesis?O Yes, since the confidence interval includes the hypothesized value of 0.O No, since the confidence interval includes the hypothesized value of 0.O Yes, since the confidence interval does not include the hypothesized value of 0.O No, since the confidence interval does not include the hypothesized value of 0.d. Interpret the results at a = 0.1.O We conclude that population mean 1 is greater than population mean 2.We cannot conclude that population mean 1 is greater than population mean 2.We conclude that the population means differ.We cannot conclude that the population means differ.

We have the survey data on the body mass index (BMI) of 659 young women. The mean BMI in the sample was x = 27.7. We treated these data as an SRS from a Normally distributed population with standard deviation σ = 7.5. Give confidence intervals for the mean BMI and the margins of error for 90%, 95%, and 99% confidence. (Round your answers to two decimal places.)

TF.17 The average number of UHD TVs sold daily at a Best Buy store is known to be 28 and approximately normally distributed. A random sample of 21 days shows sample mean x̄ = 31 with standard deviation s = 7.7. Test the hypothesis Ho : μ = 28 against Ha : μ ≠ 28 at α = 0.10 and at α = 0.05 levels of significance. Use t-distribution.

The electric cooperative needs to know the mean household usage of electricity by its non-commercial customers in kWh per day. They would like the estimate to have a maximum error of 0.14 kWh. A previous study found that for an average family the variance is 4.84 kWh and the mean is 19.1 kWh per day. If they are using a 80% level of confidence, how large of a sample is required to estimate the mean usage of electricity? Question 8 options: 45 households 1959 households 949 housholds 405 households
Our environment is very sensitive to the amount of ozone in the upper atmosphere. The level of ozone normally found is 4.6 parts/million (ppm). A researcher believes that the current ozone level is at an excess level. The mean of 14 samples is 4.9 ppm with a variance of 1.2 Does the data support the claim at the 0.01 level? Assume the population distribution is approximately normal. Step 2 of 5 : Find the value of the test statistic. Round your answer to three decimal places.
