- A survey was conducted among 68 patients admitted to a hospital cardiac unit during a two-week period. The data of the survey are shown below. Let B= the set of patients with high blood pressure. Let C= the set of patients with high cholesterol levels. Let S = the set of patients who smoke cigarettes. Answer parts (a)-(d) below. n(BNS) = 11 n(B n C) = 11 n(B ncns) = 6 n[(B nC) U (BNS) u (CNS)] = 20 n(B) = 30 n(C) = 28 n(S) = 31 ... (a) Find the number of these patients that had either high blood pressure or high cholesterol levels, but not both. The number of patients that had high blood pressure or high cholesterol levels, but not both, is 41 AA statistics professor for STAT 250 wants to investigate how long it takes students to complete Exam 1. The times that it took all 715 STAT 250 students in Spring 2022 were recorded in the data set “Time to Complete Exam 1” found in StatCrunch. The time is recorded in minutes. A student who completed the exam in 50:30 (50 minutes and 30 seconds) would be recorded as 50.5 minutes Column Mean Std. dev. Sample 26 (Time) 43.93 7.14 1) Does the mean calculated come from a sampling distribution that is approximately Normal? Check all three conditions of the Central Limit Theorem using one complete sentence for each condition to answer this question 2) Calculate the probability that, in a random sample of 26 students, the mean time to complete Exam 1 is 50 minutes or more. Complete this part by standardizing and using the Standard Normal Table to obtain this probability. Show all work and type all calculations.8 How bandwidth of operation of an electronic system controls the noise content in it ?
- Based on the chart (attached) Calculate the sum of squares (SS) for overall grade average using the definitional formulaSeveral states have argued that the 65-mph speed limit has no justification and have refused to enforce it. The federal Department of Transportation (DOT) believes that the 65-mph limit saves lives. To illustrate its contention, the department regressed the number of traffic fatalities (Y) last year in a state on the state’s population (X1), the number of days of snow cover (X2), and the average speed of all cars (X3). The results are shown below. Table 10: Model Summary Model R R Square Adjusted R Square Std. Error of the Estimate 1 .821 a .780 .613 3.258 a.

- When the measure of spread is compared between two data sets, data set A has an interquartile range of 12, and data set B has an interquartile range of 23. How do the values of data set A compare to data set B? The values of data set A are about the same on average as the values of data set B. The values of data set A are more spread out compared to the values of data set B. The values of data set A are less spread out compared to the values of data set B. The values of data set A are less on average compared to the values of data set B.A survey was conducted on how many texts (in average) students receive during an in-person class time. A survey data in a class in a particular day is given in the table. Number students Number of texts 1 20 2 14 12 4 5 If the average number texts that students received during this class time is 3, then determine the number of students (the value of x) that received 5 texts during the class time on that particular day.Explain the overidentifying restrictions test? how this can be computed?
