- Normal distribution. Let X = the number of alpha particle emissions of carbon-14 that are counted by a Geiger counter every 8 seconds. Suppose X follows an approximate Poission distribution with a mean of 4 emissions per 8 seconds. Let W = the waiting time in seconds until the 4th emission. Find: i) the complete pdf, ii) mean, iii) variance, iv) P(3.49 < x < 13.36)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.Thickness measurements of a coating process are made to the nearest hundredth of a millimeter. The thickness measurements are uniformly distributed with values 0.15, 0.16, 0.17, 0.18, 0.19. Determine the mean and variance of the coating thickness for this process. (given, required, solution)

What is the approximate t obtained value for a group of 20 psychology students who study for a mean of 10 hours per week for each 2-unit course, where the estimated population variance is 9. Would this sample be considered significantly different from the population, applying an alpha level of 0.05? t = 0.67; the sample would be considered statistically significant t = 2.24; the sample would be considered statistically significant t = 2.24; the sample would NOT be considered statistically significant t = 0.67; the sample would NOT be considered statistically significant
- An experiment was carried out to compare electrical resistivity for six different low-permeability concrete bridge deck mixtures. There were 26 measurements on concrete cylinders for each mixture; these were obtained 28 days after casting. The entries in the accompanying ANOVA table are based on information in an article. Fill in the remaining entries. (Round your answer for f to two decimal places.) You can use the Distribution Calculators page in SALT to find critical values and/or p-values to answer parts of this question.

- (i) What distribution can we assume for the number of customers coming into a DMV in Los Angeles, California, per unit time (e.g., per hour) and (ii) What distribution can we assume for the time taken to serve the customers at the Los Angeles, California DMV office? a. Normal for (i) and Uniform for (ii). b. Poisson for (i) & exponential for (ii). c. Poisson for (i) & exponential for (ii). d. Normal for (i) & exponential for (ii). e. Poisson for (i) and (ii)Emissions of sulfur dioxide by industry set off chemical changes in the atmosphere that result in "acid rain". The acidity of liquids is measured by pH on a scale of 00 to 14.14. Distilled water has pH 7.0,7.0, and lower pH values indicate acidity. Normal rain is somewhat acidic, so "acid rain" is sometimes defined as rainfall with a pH below 5.0.5.0. The pH of rain at one location varies among rainy days according to a Normal distribution with mean 5.43 and standard deviations 0.54. What proportion of rainy days have rainfall with pH below 5.0?5.0?Available below are amounts of arsenic in samples of brown rice from three different regions. The amounts are in micrograms of arsenic and all samples have the same serving size. Use a 0.05significance level to test the claim that the three samples are from populations with the same mean. Do the amounts of arsenic appear to be different in the different regions? Given that the amounts of arsenic in the samples from region Ahave the highest mean, can we conclude that brown rice from region A poses the greatest health problem?
