The sample means and variances of the observed data are needed to find the values in the sum of squares column. The given data are below. Treatment 1 Treatment 2 Treatment 3 Treatment 4 9 5 2 5 6 9 6 1 3 0 1 5 14 4 0 7 2 8 4 5 1 1 9 0 1 0 5 4 0 9 1 3 0 11 6 3 2 0 9 6 4 1 9 6 1 5 7 7 4 7 14 8 3 3 8 3 3 15 0 0 6 5 5 5 3 4 12 11 7 5 10 9 5 1 10

The sample mean number of pretzels consumed for Treatment 1, rounded to four decimal places, is calculated as follows. * 9 + 6 + 3 + ... + 12 18 = 6.0556 Find the sample means of the number of pretzels consumed for the remaining treatments, rounding your results to four decimal places. *2 = = The overall sample mean is the mean of all 74 observations and it will be used in the calculations for the variance. It is calculated below, rounded to four decimal places. + 1 + + 3 9 +6+...+5 + 9+...+2 +6+ 74 = 5.0270 The sample variance of the number of pretzels consumed for Treatment 1 is calculated as follows, with the final result rounded to four decimal places. Σ» - ) n-1 (9 - 6.0556)2 + (6 - 6.0556)2 + + (12 - 6.0556) 17 = 22.5261 Find the remaining sample variances of the number of pretzels consumed for each treatment, rounding the results to four decimal places. sz? 2 ܨ 2:
