- 3 out of 4 american adults under age 35 have eaten pizza for breakfast. if a random sample of 20 adults under age 35 is selceted, find the prob. that exactly 16 have eaten pizza for breakfastQUESTION 3It has been established that soccer ace Fernandes chances of scoring a penalty is 70 percent all thetime. However, he is a streak shooter, and if he scores on one shot, his probability of scoring it on thepenalty shot immediately following is 0.85. But it has also been pointed out that another soccer starZlatan chances of scoring a goal in any game is 65 percent all the time. However, since he is a streakstriker, and if he scores in one game, his probability of scoring in the game immediately following is0.75.3.1.Write this in the probability notation. 3.2.Calculate the probability that Fernandes will score the penalties on two consecutive shots. 3.3.Calculate the probability that Fernandes scores a penalty because Zlatan has scored twice. 3.4.Are probabilities that Zlatan scores in second game and that he scores in the third gameindependent in this question? Explain.Researchers wanted to determine whether fence lizards learned to avoid fire ants. To determine this, they gathered lizards from eastern Arkansas (where there were no fire ants), and from southern Alabama (which had been invaded by fire ants). The lizards were then exposed to fire ants, and researchers measured how long (in seconds) it took the lizards to flee. What does each dot represent? Choose the best answer. Choice 1:A difference in time to flee for a single lizard from Alabama, and a single lizard from Arkansas, assuming the null hypothesis is true. Choice 2:A difference in mean response times for one sample of lizards from Alabama, and one sample of lizards from Arkansas, which was likely to occur if the null hypothesis is true. Choice 3:A difference in response times for two lizards in our sample. Choice 4:The proportion of all lizards who will free from fire ants. Which Choice is most correct and why?
- teach me how to solve this parametric test 1. A post EPI implementation survey was conducted among 200 randomlyselected children to determine if the aim of the MHO to cover 80% of thetarget population was attained. It was found that 176 of the 200 (88%)children surveyed were immunized. Did the MHO meet his objective? b. If the cure rate for a new drug is 80%, what is the. Probability that atmost, 70% of 50 patients administered with the drug will be cured?Can you give a scenario for e and f please?A team of psychologists studied the concept of visualization in basketball, where players visualize making a basket before shooting the ball. They conducted an experiment in which 20 basketball players with similar abilities were randomly assigned to two groups. The 10 players in group 1 received visualization training, and the 10 players in group 2 did not. Each player stood 22 feet from the basket at the same location on the basketball court. Each player was then instructed to attempt to make the basket until two consecutive baskets were made. The players who received visualization training were instructed to use visualization techniques before attempting to make the basket. The total number of attempts, including the last two attempts, were recorded for each player. The total number of attempts for each of the 20 players are summarized in the following boxplots. (a) Based on the boxplots, did basketball players who received visualization training tend to need fewer attempts…

- In a winter with a flu epidemic, a well-known pharmaceutical company studied 2,000 babies to determine if the company's new drug was effective after two days. Among 120 babies who had the flu and were given the drug, 29 were cured within two days. Among 280 babies who had the flu but were not given the drug, 56 were cured within two days. Is there any significant indication to support the company's claim of the drug's effectiveness? Note:The exercise in the image is the original, it is in Spanish, but it is easy to understand.A 9-year-old girl did a science fair experiment in which she tested professional touch therapists to see if they could sense her energy field. She flipped a coin to select either her right hand or her left hand, and then she asked the therapists to identify the selected hand by placing their hand just under her hand without seeing it and without touching it. A 9-year-old girl did a science fair experiment in which she tested professional touch therapists to see if they could sense her energy field. She flipped a coin to select either her right hand or her left hand, and then she asked the therapists to identify the selected hand by placing their hand just under her hand without seeing it and without touching it. Among 257 trials, the touch therapists were correct 105 times. Use a 0.01 significance level to test the claim that touch therapists use a method equivalent to random guesses. Do the results suggest that touch therapists are effective?It is about the differantial equations...
