medical device company knows that thepercentage of patients experiencing injection-sitereactions with the current needle is 11%. A nurse willcollect data by performing injections with this type ofneedle until five people experience injection-sitereactions.Is it appropriate to use the geometric distribution tocalculate probabilities in this situation?O Yes, the geometric distribution is appropriate.No, since each trial is not independent of theother trials.O No, because it is not looking for the firstoccurrence of success.No, since the probability of success is not thesame for each of the trials.

The cost of 5 gallons of ice cream has a variance of 36 with a mean of 35 dollars during the summer. What is the probability that the sample mean would be less than 33.8 dollars if a sample of 96 5-gallon pails is randomly selected? Round your answer to four decimal places.
An asset has 0.5% chance of attack and 20% chance of the attack being successful if it happens. The asset is valued at 25 on a hundred-point scale. If an attack happens and is successful, then the asset loses 75% of its value. It is further given that the give data is 90% accurate. Calculate the risk. give clear handwritten answer!
Executives of a supermarket chain are interested in the amount of time that customers spend in the stores during shopping trips. The mean shopping time, u, spent by customers at the supermarkets has been reported to be 35 minutes, but executives hire a statistical consultant and ask her to determine whether it can be concluded that u is greater than 35 minutes. To perform her statistical test, the consultant collects a random sample of shopping times at the supermarkets. She computes the mean of these times to be 42 minutes and the standard deviation of the times to be 10 minutes. Based on this information, answer the questions below. What are the null hypothesis (H,) and the alternative hypothesis (H,) that should be used for the test? H: u is ? H: u is ? In the context of this test, what is a Type I error? A Type I error is ? fact, u is ? ? v when, in v the hypothesis that u is? v? v. Suppose that the consultant decides to reject the null hypothesis. What sort of error might she be…
The waiting time T at a bank teller’s window between two successive customers isdistributed as exponential with a mean of four minutes. Find the following probabilities:(a) P(T ≥ 5, (b) P(3 ≤ T ≤ 6), (c) P(T ≤ 4), and (d) P(T < 5). NOTE: Please explain each part, so the problem can be used as a Study Guide
Brian makes many predictions, but only 37% of them come true. The accuracy of the predictions are independent. Jack makes a bet with Joan on the next 4 days about Brian’s predictions. Jack gets 10 dollars when Brian's prediction is correct but loses 5 dollars when Brian is wrong. Let X be the total amount of money won by Jack for every correct prediction of Brian in the next 4 days. Find Jack’s expected earnings, Specify properties of expectations used if any.
Does playing Mozart for unborn babies result in having children with higher IQs? A psychologist obtains a random sample of 30 mothers in the first trimester of their pregnancy. The mothers are asked to play Mozart in the house at least 45 minutes each day until they give birth. We know that IQs are normally distributed with a mean of 100. A few years after their births the children were given an IQ test and the IQs of the 30 children in the study resulted in a sample mean of 104.2. Assume the population standard deviation for IQ of children is 15. Is there evidence that the children who listen to Mozart for at least 45 minutes each day during pregnancy have higher IQs at the 0.05 level of significance? Use the p-value approach. a. Define the parameter we are testing and setup a hypothesis test to see if the mean IQ of children who listened to Mozart at least 45 minutes a day during pregnancy is higher than the national mean of 100: b. Calculate the test statistics for this…

Please help not sure of my answers. Its statistics.
A researcher has run an experiment on the effects of early cognitive simulation on children and their school success at age 10 years. He wants to compare his sample results to the normal distribution (z-distribution), but he is not sure whether the population distribution is normal or not. He comes to you as an expert in statistics for advice. Can he do this? Why or why not? What conditions must be met?
The first pic is the question. Since some tutors have been solving the problems wrong recently (no judgment), I’ve added a sample question to solve problem.

Is there evidence that the children who listen to Mozart for at least 45 minutes each day during pregnancy have higher IQs at the 0.05 level of significance? Use the p-value approach. Select the correct conclusion for this test: We fail to reject the null hypothesis because the p-value is less than the level of significance. We fail to reject the null hypothesis because the p-value is greater than the level of significance. We…
