The melting point of 16 samples of a brand of hydrogenatd vegetable oil was determined and the sample mean came out to be 95.52. Assume that the distribution of the melting point is normal with the standard deviation of 1.5. Test H0 : µ = 95 against Ha : µ 6= 95 at the 10% significance level. Do the problem in two ways- first by obtaining the rejection region and second, by using the p-value.

The melting point of each of 16 samples of a certain brand of hydrogenated vegetable oil was determined, resulting in sample mean x bar =94.32 and the standard deviation s = 1.2. Assume that the distribution of melting point is normal. Test H0: μ=95 verses Ha: μ<95. using a significance level of 0.01.

1) Independent random samples, each containing 90 observations, were selected from two populations. The samples from populations 1 and 2 produced 21 and 14 successes, respectively. Test H0:(p1?p2)=0 against Ha:(p1?p2)?0. Use ?=0.07. (a) The test statistic is (b) The P-value is (c) The final conclusion is A. We can reject the null hypothesis that (p1?p2)=0 and accept that (p1?p2)?0. B. There is not sufficient evidence to reject the null hypothesis that (p1?p2)=0. 2)Two random samples are taken, one from among...

1.The sample mean is an unbiased estimator for the population mean. This means: The sample mean always equals the population mean. The average sample mean, over all possible samples, equals the population mean. The sample mean will only vary a little from the population mean. The sample mean has a normal distribution. 2.Which of the following statements is CORRECTabout the sampling distribution of the sample mean: The standard error of the sample mean will decrease as the sample size increases....

Question 21 Suppose a health insurance company is interested in carrying out an investigation as to the annual expenditures per household on their healthcare costs. In order to most accurately report their figures, the company decides to ensure “virtual certainty” about their estimates by using a Z value of 3.0 for their calculations. The company conducts a SRS of 843 households and determines the sample average household expenditures on healthcare is $43,257.00. A) Assume the company uses a σ=$879.00. Calculate...
