The mean of a data set is defined as:

The range of a data set equals:

If you have a data set with an even number of observations, the median is found by:

You wish to test the claim that μ = 1420 at a level of significance of α = 0.01 and a sample statistics,  x = 1390 from the sample size, n=35. Assume the population standard deviation is 82. 1. Compute the value of the standardized test statistic. Round your answer to two decimal places. 2. Find the p-value for the claim. Round your answer to two decimal places.

Scores on the math SAT are normally distributed. A sample of 17 SAT scores had a standard deviation s = 78. Construct a 95% confidence interval for the population standard deviation, σ. (L1, L2) = (                ,                )

Find the critical value, tα for 95% confidence level and n = 16.

Given the confidence interval for population proportion, 0.039 < p < 0.479. 1) Find the point estimate of the population proportion,  p ^ . 2) Find the margin of error, E.

Assume that a simple random sample has been selected from a normally distributed population and test the given claim at the 0.01 significance level. A cereal company claims that the mean weight of the cereal in its packets is 14 oz. The weights (in ounces) of the cereal in a random sample of 8 of its cereal packets are listed below.                          14.6     13.8     14.1     13.7     14.0     14.4     13.6     14.2 1) Identify the H0 and H1 2) Determine the Critical Value 3) Compute the Test Statistic 4) Find the p-value 5) Make a decision whether reject H0 or fail to reject H0 based on Critical Method or p-value method, and explain the reason for the decision. 6) Write the conclusion about the claim with word format.
