Suppose we'd like to address the power for a new RCBD study with 4 treatments and anticipate the mean of the 4 treatments can be estimated as [80,83,86,89], and the block variance is estimated as 25, and the residual variance is estimated as 55. • How much power would [5, 10, 15, 20, 25, 30] blocks provide for the ANOVA F-test on treatments? • How many blocks do you need to achieve a power of 0.8?

A random sample of 20 newly-born baby boys showed an average weight of 7.40 pounds while a sample of 25 newly-born baby girls showed a mean weight of 6.50 pounds. If the variance of all newly-born babies are 1.25 pounds, can we say that newly-born baby boys are heavier than newly-born baby girls using the 0.05 level?
Please help! I need this to graduate, thank you so much.
Hello, When I sum up the variance, I'm getting 2.75. And not 1.65. Also, how did you get the xi-mean in each column? Thanks
In swimming, clearly you would like to swim fast, but swimming consistent times is also important. A survey of 26 swims by men on a local university's swim team found a variance of their swimming times was 7 seconds. A similar survey of 21 swims by swimmers at a different university found the variance was 12 seconds. When testing the hypothesis (at the 5% level of significance) that the variances are equal, what is the test statistic? (please round your answer to 2 decimal places)
Suppose that you want to test the mean of two populations whose variance is known. Your sample size is large and yo do not have any information about α significance level. Explain how you made this decision. If your test is right tail and test statistics value is 3.12 then what would be the P-value and your decision accordingly?
What is Pooled Variance Estimate?
A study aims to compare the social media usage rates of men and women. Nine men and 9 women are drawn from the general population and the average time (in minutes) they spent on social media each day was compared (men’s mean = 40, sum of squares = 153; women’s mean = 48, sum of squares = 216). What is the (a) estimated population variance for each random sample, and (b) pooled variance? Estimated population variances = 19.13 and 27.00; Pooled variance = 23.07 Estimated population variances = 19.13 and 27.00; Pooled variance = 20.50 Estimated population variances = 17.00 and 24.00; Pooled variance = 20.50 Estimated population variances = 17.00 and 24.00; Pooled variance = 23.07
Provide one sample problem of Analysis of Variance (ANOVA)
In a comparison between the mean waiting time of the patients in the hospitals of Giza and Alexandria governments the minister of Health randomly selected 60 hospitals from Giza government and their mean waiting time was 30 minutes and the previous reports showed that the variance was 10 minutes. Also a sample consist of 50 hospitals from Alexandria governments was selected and their mean waiting time of this sample was 15 minutes and from previous reports the variance was 5 minutes. 1-Construct the 95% C.I for the difference between the average waiting time in Giza & Alex2- Without any computations, discuss fully and precisely what will happen to the results you obtained in part (1) if the confidence level changed to be 99% instead of 95%.
