- The average number of students in the college of business is 56, with a variance of 5. The calculated median was greater than the mean by 0.4. Calculate Pearson's coefficient of skewness.The amount of chlorine in 100 cm3 water taken from a water tank was measured, the average was 2.15 mg was found. The expert claims that the amount of chlorine in the water is greater than that measured. For this reason, 100 households were randomly selected, with an average chlorine content of 2.55mg and a variance of 0.49 mg. According to this data, find the account value z.

- how do you find the variance of the mean squared errors from this tabeEvery year, all incoming high school freshmen in a large school district take a math placement test. For this year’s test, the district has prepared two possible versions: Version 1 that covers more material than last year’s test and Version 2 test that is similar to last year’s test. The district suspects that the mean score for Version 1 will be less than the mean score for Version 2. To examine this, over the summer the district randomly selects 90 incoming freshmen to come to its offices to take Version 1, and it randomly selects 75 incoming freshmen to come take Version 2. The 90 incoming freshmen taking Version 1 score a mean of 113.0 points with a standard deviation of 16.8 . The 75 incoming freshmen taking Version 2 score a mean of 117.0 points with a standard deviation of 18.5 . Assume that the population standard deviations of the test scores from the two versions can be estimated to be the sample standard deviations, since the samples that are…The analysis of variance methodology will show that there really is a difference between the means of several groups when: the variance within groups is significantly larger than the variance between groups. the variance between groups is significantly larger than the variance within groups. the sum of squares within groups is large relative to the sum of squares total. the sample means across the treatment groups are identical and equal the grand mean.
