From the provided information, The difference table can be obtained as: di = Before - After 7 9 2 -5 14 -2 12 Sample size (n) = 7The mean and standard deviation of difference can be obtained as:The hypotheses are as follow: H0: µd = 0 H1: µd > 0 Level of significance (α) = 0.01 Since, the population standard deviation is unknown, therefore, the t distribution will be used. The value of the test statistic can be obtained as:The degree of freedom = n – 1 = 7 – 1 = 6 The critical value of t at 6 degree of freedom with 0.01 level of significance from the t value table is 3.1426. The test statistic value lies in the critical region therefore, the null hypothesis would reject and it can be concluded that there is sufficient evidence to support the claim that the diet is effective in reducing weight.

The test was designed to research whether the blood sugar level depends on age. 100 randomly chosen people of different ages took part in the study. People were divided into groups depending on their ages. Scientists measured the blood sugar level in each group. The results are placed in the table below. Age group n Mean (mmol/l) 20-30 30 - 40 40 - 50 50+ 25 25 25 25 4.9 4.8 5.1 5.3 Std.Dev. 0.59 0.73 0.61 0.65 Do we have any evidence that age affects the blood sugar level? Use a 5% significance level. Because of a rather small p-value, we can't make a conclusion that there is a difference in means. O Because of a very large p-value, we can't make a conclusion that there is a difference in means. Because of a rather small p-value, we can make a conclusion that the blood sugar level depends on age. Because of a very large p-value, we can make a conclusion that there is a difference in means.
Weights (kg) of poplar trees were obtained from trees planted in a rich and moist region. The trees were given different treatments identified in the accompanying table. Use a 0.05 significance level to test the claim that the four treatment categories yield poplar trees with the same mean weight. Is there a treatment that appears to be most effective? LOADING...

Below indicate whether the appropriate test would be an independent t-test, dependent t-test, One-way ANOVA, or z-test. A researcher wants to know if people find baby animals cuter than adult animals. All of the participants in a study are shown 10 pictures of baby animals and 10 pictures of adult animals. They are asked to rate (on a 1 to 10 scale) how cute they think each animal is.
Dr. Blake is interested in the effects of intoxication on driving ability. Participants are recruited and encouraged to consume one to four mixed drinks during a one-hour period.
