If, in a sample of n= 25 selected from a normal population, X= 51 and S= 15, what is your statistical decision if the level of significance, a, is 0.10, the null hypothesis, Ho, is u= 50, and the alternative hypothesis, H, , is µ#50? a. Determine the critical value(s). The critical value(s) is(are). (Round to four decimal places as needed. Use a comma to separate answers as needed.) b. Determine the test statistic, tSTAT STAT =D (Round to four decimal places as needed.) c. State your statistical decision. Choose the correct answer below. O A. The test rejects the null hypothesis. The data does not provide sufficient evidence to conclude that the mean differs from u = 50. O B. The test rejects the null hypothesis. The data provide sufficient evidence to conclude that the mean differs from u = 50. OC. The test does not reject the null hypothesis. The data provide sufficient evidence to conclude that the mean differs from u = 50. O D. The test does not reject the null hypothesis. The data does not provide sufficient evidence to conclude that the mean differs from u = 50.

Two separate samples are selected from the same population. Each have an n=8. Both samples receive a different treatment. After the treatment, the first sample has SS=16 and the second sample has SS=24. With a mean of 3 for the first group and mean of 6 for the second group, compute the t statistic. State the conclusion of these findings.
26 The table to the right shows the cost per ounce (in dollars) for a random sample of toothpastes exhibiting very good stain removal, good stain removal, and fair stain removal. At α=0.01, can you conclude that the mean costs per ounce are different? Perform a one-way ANOVA test by completing parts a through d. Assume that each sample is drawn from a normal population, that the samples are independent of each other, and that the populations have the same variances.

Bags of a certain brand of tortilla chips claim to have a net weight of 14 oz. Net weights actually vary slightly from bag to bag and are Normally distributed with mean u. A representative of a consumer advocate group wishes to see if there is any evidence that the mean net weight is less than advertised, so he intends to test the hypotheses Ho: μ = 14, Ha: μ < 14. To do this, he selects 16 bags of this brand at random and determines the net weight of each. He finds the sample mean to be x = 13.88 and the sample standard deviation to be s = 0.24. Suppose in a similar test of 16 bags of these tortilla chips the P-value is 0.001. Further suppose that a is chosen to be 0.001. In that case, we would conclude that: Othere is not significant evidence that the mean net weight of the bags of chips is less than the advertised 14 oz. O there is not significant evidence that the mean net weight of the bags of chips is not less than the advertised 14 oz. O there is significant evidence that the…
