I need the test statistic and p-value please and please show work and formula. Thank you!    In an early Gregor Mendel’s study, he crossed two hybrid pea plants and recorded theform (round or wrinkled) and albumen color (yellow or green) of the fertilized seed. Hetheorized that these should appear in the following proportionsRound, Yellow Wrinkled, Yellow Round, Green Wrinkled, Green9/16 3/16 3/16 1/16The observed counts were as follows:Round, Yellow Wrinkled, Yellow Round, Green Wrinkled, Green Total315 101 108 32 5560. What are the expected counts?Round, Yellow Wrinkled, Yellow Round, Green Wrinkled, Green Total556Test to see if the observed counts confirm Mendel’s theory. Use ? = 0.05.1. State the null and the alternative hypothesis using the proper notation established in class. Ho:Ha:2. Is there a random sample?Are all expected counts at least 5?Proceed even if the conditions are not satisfied3. What is the significance level?How many degrees of freedom are associated with this…

the accuracy of a coin counter machine is gauged to accepts nickels with a mean diameter of millimeters 21.21 mm. A sample of 37 nickles was drawn from a reported defective coin-countermachine located near a school. The sample had a sample mean of 21.213 mm and sample standarddeviation 0.01 mm.Test the claim that the mean nickel diameter accepted by this coin-counter machine is greaterthan 21.21 mm. Test at the 0.01 significance level. (Identify the null and alternate hypothesis, teststatistic value, critical value , Determine reject or fail to reject H0

Webster Chemical Company produces mastics and caulking for the construction industry. Theproduct is blended in large mixers and then pumped into tubes and capped.Webster is concerned whether the filling process for tubes of caulking is in statistical control. Theprocess should be centered on 8 ounces per tube. Several samples of eight tubes are taken andeach tube is weighed in ounces. Assuming that taking only 6 samples is sufficient, is the processin statistical control?     Tube 1  Tube 2 Tube 3 Tube 4 Tube 5 Tube 6 Tube 7 Tube 8 Sample 1 7.98 8.34 8.02 7.94 8.44 7.68 7.81 8.11 Sample 2 8.23 8.12 7.98 8.41 8.31 8.18 7.99 8.06 Sample 3 7.89 7.77 7.91 8.04 8.00 7.89 7.93 8.09 Sample 4 8.24 8.18 7.83 8.05 7.90 8.16 7.97 8.07 Sample 5 7.87 8.13 7.92 7.99 8.10 7.81 8.14 7.88 Sample 6 8.13 8.14 8.11 8.13 8.14 8.12 8.13 8.14

Product filling weights are normally distributed with a mean of 350 grams and a standarddeviation of 15 grams.a. Develop the control limits for the x_chart for samples of size 10, 20, and 30.b. what happens to the control limits as the sample size is increased?c. what happens when a Type I error is made?d. what happens when a Type II error is made?e. what is the probability of a Type I error for samples of size 10, 20, and 30?f. what is the advantage of increasing the sample size for control chart purposes? whaterror probability is reduced as the sample size is increased?

uestion Q2. Borneo Steel Corporation produces iron rings that are supplied to ARAAB Co. Ltd. These rings are supposed to have a diameter of 60 cm. The machine that makes these rings does not produce each ring with diameter of exactly 60 cm. The diameter of each of the rings varies slightly. It is known that when the machine is working properly, the rings made on this machine have a mean diameter of 60 cm. The quality control department takes a random sample of 35 such rings every week, calculates the mean of the diameters for these rings and makes a 99% confidence interval for the population mean. If either the lower limit of this confidence interval is less than 59.938 cm or the upper limit of this confidence interval is greater than 60.063 cm, the machine is stopped and adjusted. A recent sample of 35 rings produced a mean diameter of 60.038 cm with a standard deviation of 0.15 cm. Based on this sample can you conclude that the machine needs an adjustment?

An advertising agency is studying social media campaigns and how they impact website traffic. The advertising agency states the average increase in website traffic after a social media campaign is greater than 20 percent. If we would like to test the advertising agency's claim with a hypothesis test using a significance level of a = 0.025 , what is the rejection region? Use the graph below to show the rejection region. First, move the blue dot to choose the appropriate test (left-, right, or two- tailed). Then, slide the shaded region(s) to represent the rejection region. Provide your answer below: Move the blue dot to choose the appropriate test Rejection region= 0.255 -2 Current rejection region = 0.255

Five samples of a ferrous-type substance were used to determine if there is a difference between a laboratory chemical analysis and an X-ray fluorescence analysis of the iron content. Each sample was split into two subsamples and the two types of analysis were applied, with the accompanying results. Assuming that the populations are normal, test at the 0.02 level of significance whether the two methods of analysis give, on the average, the same result. Click here to view the sample analyses. Click here to view page 1 of the table of critical values of the t-distribution. Click here to view page 2 of the table of critical values of the t-distribution. Let sample 1 be the X-ray fluorescence results and let sample 2 be the laboratory chemical results. State the null and alternative hypotheses. Ho: HD H1: HD + Identify the critical region.
