Number of zeros: one X NOTE: Enter an exact value for the zero or round to three decimal places. be here to search X = -5+√11 2 O X
- A drug company creates a medicine designed to prevent colds, and states that it is equally effective for men and women. To test this claim, they give the medicine to 100 men and 200 women. At the end of the study, 33 men and 95 women caught a cold. Can we say that the drug is equally effective for men and women? (Use α = .01)Help with 9Pls help ASAP
- Heights (cm) and weights (kg) are measured for 100 randomly selected adult males, and range from heights of 135 to 188 cm and weights of 39 to 150 kg. Let the variable x be the height. The 100 paired measurements yield x=167.08 cm, y=81.32 kg, r=0.254, and y=−109+1.07x. Find the best predicted value of y (weight) given an adult male who is 163 cm tall. Use a 0.05 significance level. The best predicted value of y for an adult male who is 163 cm tall is kg. (Round to two decimal places as needed.)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:An oil company is considering introducing an additive into its gasoline, hoping to increase the average mileage per liter.. The engineers at the oil company's group are considering introducing an additive into their gasoline, hoping to increase the average mileage per liter. The research group's engineers tested engineers tested 32 cars with regular gasoline and another 39 cars with gasoline containing the additive. With the additive. From previous studies it is estimated that: Mileage per liter without additive: μ = 14.2 km, s = 3.24 km Mileage per liter with additive: u = 15.4 km, s = 5.56 km. a) What is the probability that the average kilometers traveled per liter in the sample of cars with additive is greater than 14.8 km? of cars with additive is greater than 14.8 km? b) If it is estimated that the variances of the kilometers traveled with and without additive are the same, what is the probability that in the samples, the average kilometers traveled per liter with the new…
- 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…Parts D and EThe volume of cola of Brand A and Brand B filled into a bottle are uniformly distributed.Brand A: between 1.45 and 1.53 liters.Brand B: between 1.44 and 1.53 liters.Both brands claim that their cola contain more than 1.50 liters.
