The Food and Drug Administration has determined that a substancecalled Melamine poses a health threat when it contaminates food. Infact, it poses a health threat even to dogs when it is in their food.Consequently, the FDA wants to monitor shipments of dog foodimported into the country. From previous studies on dog food, theFDA knows that the population mean of Melamine in dog food is 8.0grams in a 40 pound bag, with a population standard deviation of 1.5grams.How likely would it be that a random sample of 36 40-pound bags ofdog food would have a mean of more than of 8.4 grams of Melamineper bag?All bags have at least 8 grams0.050.50None of the bags will have less than 8 grams

There is a normal distribution with mean 10 and standard deviation of 8. What is the z-score of a group of 16 observations averaging 15?
Americans spend an average of 23.6 hours per week online, with a standard deviation of 7. The distribution of internet watching is not necessarily normally distributed. Suppose you took a random sample of 50 people. What is the probability that the sample average will be less than 23 hrs? Round your answer to three decimal places, eg 0.628.
A manufacturer claims that the calling range (in feet) of its 900-MHz cordless telephone is greater than that of its leading competitor. A sample of 1010 phones from the manufacturer had a mean range of 11801180 feet with a standard deviation of 4141 feet. A sample of 2020 similar phones from its competitor had a mean range of 11101110 feet with a standard deviation of 3535 feet. Do the results support the manufacturer's claim? Let μ1�1 be the true mean range of the manufacturer's cordless telephone and μ2�2 be the true mean range of the competitor's cordless telephone. Use a significance level of α=0.01�=0.01 for the test. Assume that the population variances are equal and that the two populations are normally distributed. Step 2 of 4 : Compute the value of the t test statistic. Round your answer to three decimal places.

Assume that you are working for the Consumer Protection Agency and have recently been getting complaints about the highway gas mileage of the new Dodge Caravans. Chrysler Corporation agrees to allow you to randomly select 40 of its new Dodge Caravans to test the highway mileage. Chrysler claims that the Caravans get 28 mpg on the highway. Your results show a mean of 26.7 and a standard deviation of 4.2. You support Chrysler’s claim. 1. Show whether or not you support Chrysler’s claim by listing the P-value from your output.After more complaints, you decide to test the variability of the miles per gallon on the highway. From further questioning of Chrysler’s quality control engineers, you find they areclaiming a standard deviation of no more than 2.1. Use a one-tailed test.2. Test the claim about the standard deviation.3. Write a short summary of your results and any necessary action that Chrysler must take toremedy customer complaints.4. State your position about the necessity to…
