- A survey was conducted among 50 PUP students to know the brand of vaccine they had for the first 2 doses and their booster. The responses were tallied and revealed that 20 students had both Sinovac and Astrazenica while 17 has Astrazenica only and 10 had Sinovac only. How many from these students were vaccinated with Sinovac or Astrazenica?z-test or t-test. show the result of the table in excel. upvote will be given. (YOU MAY USE EXCEL IN SOLVING THE PROBLEM.

- A doctor wants to develop a pill to help people with peanut allergies. Her goal is to prevent the dangerous symptoms that occur when a person allergic to peanuts contacts the nuts. She splits her patients into two groups. The first group receives the new pill, and the second group receives a pill with inactive ingredients. Over the course of a couple of months, all patients are tested for desensitization of peanuts. Treatment: Placebo:There is no cure for the common cold, but many cold remedies claim to make you feel better faster. A consumer watch group decides to compare the effectiveness of Vitamin C to the effectiveness of Echinacea in lessening the duration of the common cold. Sixty participants have volunteered to be infected with the cold virus for this study. In addition to the Vitamin C and Echinacea treatments which will be administered in capsules that are identical in appearance, one of the researchers suggests that they add a group that receives no treatment but receives an identical looking capsule with an inactive ingredient. If they decide not to add a group that receives no treatment, then: (A) This study will not be an experiment since there will not be a control group. (B) Even if there is a difference in recovery time between the Vitamin C and Echinacea groups, we will not know if the recovery times are less than if no treatment were given. (C) The experimental design will not be taking into…Please help me do this case study with explanations with the answers and the calculations on excel CASE STUDY: Ya Ya's Yogurt. Last year Ya Ya Yogurt's decided to enter the flavored yogurt market, and it began cautiously by producing, distributing, and marketing a single flavor—a blueberry-flavored yogurt. The company’s initial venture into the yogurt market has been very successful; sales of blueberry are higher than expected, and consumers’ ratings of the product have a mean of 80 and a standard deviation of 25 on a 100-point scale for which 100 is the most favorable score and zero is the least favorable score. Past experience has also shown Ya Ya's that a consumer who rates one of its products with a score greater than 75 on this scale will consider purchasing the product, and a score of 75 or less indicates that the consumer will not consider purchasing the product. Emboldened by the success and popularity of its blueberry-flavored yogurt, Ya Ya's management is now considering the…
