potato chips weight is more than 150 grams. The weight of the bag has a normal distribution. Because of the complaints of the customers, quality control department select randomly 49 bags and find the mean as 146 grams and variance 9 grams. Test the manufacturer claim at 5 9% level of significance. Find the correct answer for the hypothesi and find the correct answer for critical value.

The average triglyceride level of adult males is 126 milligrams per deciliter. You want to determine whether the true mean male triglyceride level is more than the average. You decide to pull a random sample of eight adult males and measure their triglyceride level. You find the sample mean is 127.9 milligrams per deciliter and the standard deviation is 4.12 milligrams per deciliter. What are the test statistic and the p-value? O The test statistic is 1.9 and the p-value is 0.1174. O The test statistic is 0.1174 and the p-value is 1.9. O The test statistic is 1.46 and the p-value is 1.30.

The population average for SAT scores is known to be 500 with a standard deviation of 100. This distribution is approximately normal. Fifteen (15) high school students complete a preparation programme for taking the SAT test and obtain a mean score of 620. What would be the most appropriate statistical test for determining whether student who took the SAT preparation program obtained significantly greater score than the population mean? Explain your answer.

Avalanches can be a real problem for travelers in the western United States and Canada. Slab avalanches studied in Canada had an average thickness of u = 67 cm. A sample of 31 avalanches in the U.S. gave a sample mean of = 63.0 cm. It is known that o = 10.3 cm for this type of data. Use a 0.03 level of significance to test the claim that the mean slab thickness of avalanches in the United States is different from that in Canada. Use the P-Value Approach. What are the hypotheses for this problem? А: Но и 3D 63.0 ст us На и + 63.0 ст B: Но и 63.0 ст С: Но и %3D 67 ст us HA и < 67 ст D: Ho u = 67 cm vs HA H# 67 cm B O A

Two or more samples are often compared when we suspect that there are differences between the groups—for example, are cancer rates higher in one town than another, or are test scores higher in one class than another? In your chosen field, when might you want to know the mean differences between two or more groups? Please describe the situation (what groups, what measurements) including how and why it would be used.
There is a new medication for diabetes, fifteen participants take the medication for fifteen days. The average blood glucose before taking the medication was 155 (population mean). The average blood glucose after taking the medication is 110. The standard deviation for the average glucose after taking the medication is 4.6. You want to evaluate if there is statistical evidence that there is a reduction in the mean glucose after taking the medication for 15 days. You must conduct a t-test. What is the t-statistic?
