Suppose that three microchips in a production run of thirty are defective. A sample of five is to be selected to be checked for defects.(a) How many different samples of five can be chosen from the production run of thirty?MY NOTES(b) How many samples will contain at least one defective chip?The set of samples that do not contain any defective chips and the set of samples that contain at least one defective chip are ---Select--- sets. So, the number of samples with at least one defective chip is(c) What is the probability (as a percent) that a randomly chosen sample of five contains at least one defective chip? (Round your answer to one decimal place.)%

3. The juror pool for the upcoming murder trial of a celebrity actor contains the names of 100000 individuals in the population who may be called for jury duty. It is known that 40% of the available jurors in the pool are Hispanics. A jury of size 12 is selected at random from this pool (that each of the 100000 individuals is equally likely to be selected). LetX = the number of Hispanics selected to be jurors for this jury. (a) Is it reasonable to assume that X has an (approximate) binomial distribution? If so, please i) specify what constitutes a Bernoulli trial in this case , ii) verify the Binomial conditions, and iii) identify the values ofn and p. If not, explain why not.

Let's assume that the COVID-19 new case report data were collected from S.A Ministry of Health 30th of December 2019 was the first date that COVID-19 was confirmed in S.A. The time period of data was from the 20th of January to the 27th of January 2020 (for the last 7 days). The data included the total number of new cases, date of recorded, number of new total COVID-19 cases. In this study, a medical researcher used Pearson's cortelation analysis and the linear regression model to predict COVID-19 new cases based on the available data. (e.g., that Cases of infection rises linearly with number of people tested). The best-known types of regression analysis are the following: Date Day Sunday Monday Tuesday Wednesday Thursday Friday Saturday Sunday Test No. Case Counts 2020/01/20 2020/01/21 2020/01/22 2020/01/23 2020/01/24 2020/01/25 2020/01/26 2020/01/27 6. 33 41 17 1 18 3. 13 44 Calculate the coefficient of correlation using the Karl Pearson method.

Nationally, patients who go to the emergency room wait an average of 7 hours to be admitted into the hospital. Do patients at rural hospitals have a lower waiting time? The 14 randomly selected patients who went to the emergency room at rural hospitals waited an average of 5.8 hours to be admitted into the hospital. The standard deviation for these 14 patients was 1.7 hours. What can be concluded at the the αα = 0.05 level of significance level of significance?
