In a completely randomized experimental design involving four treatments, 20 observations were recorded for each of the four treatments. The following information is provided: SSTR = 154 and SST = 342. What does the sum of squares within treatments (SSE) equal?
Let p1 and p2 be the respective proportions of women with iron-deficiency anemia in each of two developing countries. A random sample of 1900 women from the first country yielded 513 women with iron-deficiency anemia, and an independently chosen, random sample of 1700 women from the second country yielded 515 women with iron-deficiency anemia. Can we conclude, at the 0.10 level of significance, that the proportion of women with anemia in the first country is less than the proportion of women with anemia in the second country? Perform a one-tailed test. Then complete the parts below.Carry your intermediate computations to three or more decimal places and round your answers as specified in the parts below.
a. State the null hypothesis H0 and the alternative hypothesis H1.
b. Find the values of the test statistic.
c. FInd the p-value.
d. Can we conclude that the proportion of women with anemia in the first country is less than the proportion of women with anemia in the second country?
A random sample of a size n = 25 is obtained from a population with a variance of σ2 = 400, and the sample mean is computed to be x̅ c = 70. Consider the null hypothesis H0: μ = 80 versus the alternative hypothesis H1: μ = 80. Compute the p-value for this test
