Question 5The proper operation of web-based applications on a phone requires broadband speeds that do not varymuch. Listed below are 13 broadband speeds (in Mbps) measured on 13 different days.121.3 148.8 137.7 171 126.7173.4145.2 174.1 153 143.5160145.8 146.9The mean of the data set is 149.8; the sample standard deviation is 16.557; if the normality plot is notprovided you may assume that the broadband speeds are normally distributed.100 MbConstruct a 99% confidence interval for the variance (standard deviation) of broadband speed for theservice provider.i.

Use the given data values (a sample of female arm circumferences in centimeters) to identify the corresponding z scores that are used for a normal quantile plot, then identify the coordinates of each point in the normal quantile plot. Construct the normal quantile plot, then determine whether the data appear to be from a population with a normal distribution. 33.9, 37.9, 43.8, 32.8, 40.1 Question content area bottom Part 1 List the z scores for the normal quantile plot. Part A -List the z scores for the normal quantile plot. Part B- Identify the coordinates of each point in the normal quantile plot. Use ordered pairs for the form (x,y), where x is the sorted arm circumferences in ascending order, and y is the corresponding z score. Part C- Do the data come from a normally distributed population?

Choose the appropriate statistical test. When computing, be sure to round each answer as indicated. A dentist wonders if depression affects ratings of tooth pain. In the general population, using a scale of 1-10 with higher values indicating more pain, the average pain rating for patients with toothaches is 6.8. A sample of 30 patients that show high levels of depression have an average pain rating of 7.1 (variance 0.8). What should the dentist determine? 1. Calculate the estimated standard error. (round to 3 decimals). [st.error] 2. What is thet-obtained? (round to 3 decimals). 3. What is the t-cv? (exact value) 4. What is your conclusion? Only type "Reject" or Retain"

Autopitch devices are made for both major- and minor-league teams to help them improve their batting averages. When set at the standard position, Autopitch can throw hardballs toward a batter at an average speed of 53 mph. To monitor these devices and to maintain the highest quality, Autopitch executive Neil Geismar takes samples of 9 devices at a time. The average range is 4 mph. a) Using this information, construct control limits for the x-chart. UCL,-mph (round your response to three decimal places). LCL, mph (round your response to three decimal…
