A nutritionist claims that the average sodium content in a certain brand of soup is less than 600 mg per serving. A random sample of 8 cans has the following sodium contents (in mg): Sample (mg): | 590 | 610 | 580 | 595 | 605 | 575 | 585 | 600 | Our alpha is a =0.05. Our hypotheses are: Ho: μ = 600 vs. Ha: μ < 600 (one-tailed test) The sample standard deviation (s) = 12.25 Calculate the sample mean. Compute the t-statistic. Determine the degrees of freedom. Find the critical value for this example from Table C. Decide whether to reject or fail to reject Ho.
