The data below shows the sugar content in grams of several brands of children's and adults' cereals. Create a 95% confidence interval for the difference in the mean sugar content, Ic - HA. Be sure to check the necessary assumptions and conditions. (Note: Do not assume that the variances of the two data sets are equal.)

The researchers randomly assigned volunteers to watch one of three programs. each containing the same nine commercials. The shows were either violent, sexual, or neutral.

Since the P-value is less than 0.05, the null hypothesis that there is no difference between the two programs cannot be rejected. 0 D. Since the P-value is less than 0.05, the null hypothesis that there is no difference between the two programs is rejected. b.) Is there evidence that viewer memory for ads may differ between programs with sexual content and those with neutral content? Test an appropriate hypothesis and state your conclusion.
