Find the 90% PI for asingle new value from the population.In a sample of 103 bags of dog food, the average weight was found to be 21.5lb with a standard deviation of 0.5. Give a point estimate for the population variance of the weight of the bags of dog food. Round your answer to two decimal places, if necessary.An agriculture publication claims that the population mean of the birth weights for all Suffolk sheep is 4.29 kg. A veterinary service has hired you to test that claim. To do so, you select a random sample of 35 Suffolk sheep and record the birth weights. Assume it is known that the population standard deviation of the birth weights of Suffolk sheep is 2.15 kg. Based on your sample, follow the steps below to construct a 99% confidence interval for the population mean of the birth weights for all Suffolk sheep. Then state whether the confidence interval you construct contradicts the publication's claim. (If necessary, consult a list of formulas.) (a) Click on "Take Sample" to see the results from your random sample of 35 Suffolk sheep. Take Sample Number of sheep 35 Sample mean 5.52 deviation Sample standard Population standard deviation 1.78 2.15 Enter the values of the sample size, the point estimate for the population mean, the population standard deviation, and the critical value…
- In a school district, all sixth grade students take the same standardized test. The superintendant of the school district takes a random sample of 26 scores from all of the students who took the test. She sees that the mean score is 184 with a standard deviation of 18.2982. The superintendant wants to know if the standard deviation has changed this year. Previously, the population standard deviation was 17. Is there evidence that the standard deviation of test scores has increased at the α=0.01 level? Assume the population is normally distributed. Step 1 of 5 : State the null and alternative hypotheses. Round to four decimal places when necessary.What is the meaning of x ~ N (50, 20)? 1.
