Marketing research .. project - Essay Example With 95% confidence interval; it means that we accept the null hypothesis that the mean response to X166-reasonable Prices are lower than 6 and reject the alternative hypothesis that the mean response to X166-reasonable prices are higher than 6. From a practical standpoint, the results of the Univariate hypothesis test showed that respondents perceived the menu were significantly lower than 6 and this can be reflected by the mean of 4.508641975 for X14 and 4.338271605 for X16. The mean values for X22 and X32 are 4.82963 and 0.348148148 respectively. To determine if the two mean are significantly different with an equal variance, a t-statistical analysis is undertaken. The one tail results give a t-critical of 1.647649 while the two tail gives a t-critical result of 1.964318. However; going by the one tail, the t-critical is 1.647649 compared with a significance level of 0.00, we accept the null hypothesis that the two means are statistically significant. According to the book page 498, this analysis was supposed to compare the level of satisfaction between male and female-considering the mean. However, from the results there is no substantial support for the null hypothesis to ascertain that the two means are equal, and hence we conclude that male customers are significantly more satisfied than female customers. The mean values of X21, X22 and X23 are 4.82963, 4.464198 and 3.785185. The null hypothesis is to test if the mean of the variables are significantly different. The p-value=3.59 while the significant level ÃŽ ±=o.05; therefore we accept the null hypothesis that the mean of the variables are significantly different (p-value>0.05). That is, the mean perceptions of males between the two restaurants do not differ significantly on satisfaction or likelihood of
