The confidence interval for the first group mean is thus (4.1, 13.9). Similarly for the second group, the confidence interval for the mean is (12.1, 21.9). Notice that the two intervals overlap. However, the t-statistic for comparing two means is: t= 17 − 9 2.5 2 + 2.5 2 = 2.26 which reflects that the null hypothesis, that the means of the two groups are the same, should be rejected at the α = 0.05 level. To verify the above conclusion, consider the 95 percent confidence interval for the difference between the two group means: (17 − 9 ) ± 1.96 × 2.5 2 + 2.5 2 which yields (1.09, 14.91).
Graphics Analysis Today I will be reporting on three graphics; one a popular coffee branch logo 'Starbucks Coffee', the other a 'Chanel No5' advert, and the last, a ‘Andrex’ toilet paper advert.

It is a “lighter, mellower roast coffee developed to meet the demands of consumers who requested that Starbucks create a lighter-roasted coffee.” According to Smyl & Edelman (2012), Brad Anderson, master roaster for Starbucks, said of Starbucks customers, “They told us they wanted a flavorful, lighter-bodied coffee that offers a milder taste and a gentle finish.

Since length of labor provides interval/ratio data so Range can also be used to analyze the data. 4. The distributions of scores in control and experimental groups for the length of labor are not similar neither it is significantly different for the groups. The mean (M) for the length of labor indicates (12.79 control group and 14.63 experimental group), 1.84 variation. The standard deviation (SD) for the length of labor indicates (7.78 experimental group and 7.2 control group), a variation of 0.58.
