A lumberyard has a machine that is designed to cut deck Based on the scenario, identify the appropriate boards to a length of 14 feet. The manager of the lumberyard is concerned that the machine is not cutting the boards the correct length. He takes a random sample of 17 boards and records their lengths. Do these data provide convincing evidence at the a = 0.05 level that the mean length of the cut boards differs from 14 feet? Let u = the true mean length of the deck boards. hypotheses to use to conduct a significance test. Ho: H = 14 feet; H, µ > 14 feet Ho: H= 14 feet; Ha: H = 14 feet Ho: H = 14 feet; Ha: H = 14 feet x = 14 feet; H,: x = 14 feet Data: 13.89, 13.90, 13.95, 13.98, 13.99, 14.0, 14.02, 14.05, 14.08, 14.1, 14.15, 14.18, 14.2, 14.21, 14.23, 14.25, 14.3

The blue catfish (Ictalurus Furcatus) is the largest species of North Amercian catfish. The current world record stands at 143 pounds, which was caught in the John H. Kerr Reservoir (Bugg's Island Lake) located in Virginia. According to Amercian Expedition, the average weight of a blue catfish is between 20 to 40 pounds. Given that the largest blue catfish ever caught was at the John H. Kerr Reservoir, you believe that the mean weight of the fish in this reservoir is greater than 40 pounds. Use the data below, which represents the summary statistics for 50 blue catfish caught at this reservoir, and a 0.05 significance level to test the claim that the mean weight of the fish in the John H. Kerr Reservoir is greater than 40 pounds. n=50;  ¯x=40.72 pounds;  s=5.03pounds Calculate your test statistic. Write the result below, and be sure to round your final answer to two decimal places.e) Calculate your p-value. Write the result below, and be sure to round your final answer to four decimal…

For the project, you will have to: Collect and organize a sample of 30 items of data from a source you find relevant. Some examples: Sports (top HR hitters, rushing leaders, point scorers, etc.) Weather (average daily temperature for a month, max hurricane wind speed, etc.) Business (top-grossing movies, highest-paid athletes, record sales, etc.) Demographics (age, height, weight, etc.) Find the mean, median, mode, and mid-range for your date. Find the variance, standard deviation, and range for your data. Find the five-number summary and determine (mathematically) if there are any outliers. Construct a 95% confidence interval for the mean of your data.       You are allowed to use the calculator for the calculations but you must provide me with the 30 data values you obtain in a neat, organized manner, preferably in a spreadsheet. Also, be sure to provide the source of your data. When you provide the answers to the questions above please use the correct symbols and notation.…
