Kruskal Wallis

Kruskal Wallis 4

An instructor divided her class into four groups and asked them to keep track of the number of soft drinks that they consume per week. The data has been ranked and the sums determined for each group.

Soft Drinks Consumed per Week

Group A 7 10 14 12 8

Group B 4 20 6 11 9

Group C 2 5 13 15 10

Group D 3 9 16 17 18

The sums of the ranks for the four groups is as follows:

RA = 51.5 ;RB = 48.5 ;RC = 45.5 ;RD = 64.5

Complete the Kruskal-Wallis test to determine if the hypothesis that the different groups consume the same amount of soft drinks per week is valid at α = 0.05

An estimate from a bus company is that young adults took 4.5 Uber rides 6

An estimate from a bus company is that young adults took 4.5 Uber rides each year. A student randomly polls 30 young adults and finds that these young adults have taken an average of 4.5 Uber rides each year with a standard dev of 1.2 rides. i) With significan level of 0.05 , do the test claim (Ho, Ha, critical value(s), test statistic , p-value, conclusion). ii) Come up with your own confidence level that is equivalent to the significant level of 0.05. iii) find confidence interval to estimate the population means with confident level from part ii. iv) interpret the result from the confidence interval

A researcher want to determine whether the blood pressure of Kombucha drinkers

A researcher want to determine whether the blood pressure of Kombucha drinkers 7

A researcher want to determine whether the blood pressure of Kombucha drinkers is, on average, lower then the blood pressure of non-Kombucha drinkers. Independent simple random samples of 85 Kombucha drinkers and 75 non-Kombucha drinkers yielded the following sample statistics for systolic blood pressure: Kombucha drinker n1 = 85 xbar1 = 124.1 s1= 38.7 Non -Kombucha drinker n2= 75 xbar2 = 138.7 s2= 39.2. Use a significance level of 0.10 to test the claim that the mean systolic blood pressure of Kombucha drinkers is lower than the mean systolic blood pressure of non-Kombucha drinkers.

of the population has the changed since 2010? Same questions like the previous one.
