An article in the journal Applied Nutritional Investigation reported the results of a comparison of two different weight-loss programs (Liao, 2007). In the study, obese participants were randomly assigned to one of two groups and the percent of body fat loss was recorded. The soy group, a low-calorie group that ate only soy-based proteins (M= 4.2, s=0.75), while the traditional group, a low-calorie group that received 2/3 of their protein from animal products and 1/3 from plant products (M= 5.3, s=0.41). If SM1-M2 = 0.25, s²pooled = 0.35, n1 = 10, n2 = 12 is there a difference between the two diets. Use alpha of .05 and a two-tailed test to complete the 4 steps of hypothesis testing.

Question

please show work and state which test was used ( single sample t test, paired sample t test, independent sample t test)

the box reaches its sale
weight. To determine whether a similar number of raisins are poured into each box,
you randomly sample 25 boxes about to leave the plant and count the number of
raisins in each. You find the mean number of raisins in each box to be 33.2, with s =
2.43. Perform the 4 steps of hypothesis testing to determine whether the average
number of raisins per box differs from the expected average 35. Use alpha of .05 and
a two-tailed test.

A social worker is interested in examining how people who have higher levels of
psychological resiliency respond after a natural disaster. She obtained anxiety
scores, which were measured on a scale of 1-12 with higher numbers meaning more
anxiety, from eight individuals who had experienced a natural disaster. She
collected these scores 3 weeks after the disaster (M=9.75) and 6 months after the
disaster (M=525) She expected that the anxiety scores at 6 months would be much
