Speed cameras (SC) are used to reduce the risk ofaccidents in accident-prone zones in metropolitan cities. To study the effectiveness ofspeed cameras, transport engineers would like to compare the average number ofaccidents in junction A (with SC) and junction B (without SC). The number ofaccidents in 105 weeks in two junctions are provided below.6 7+Number of Accidents 0 1 2 3 4 5Observed frequency 40 20 15 16 10 3 1 0Number of Accidents 0 1 2 3 4 5 6 7+Junction Bwithout SC Observed frequency 25 24 18 15 18 41 0Junction Awith SCTest the average number of accidents per week in junctions A and B are same atthe 5% significance level.

Chapter 6, Section 2-CI, Exercise 108 Plastic Microfiber Pollution on ShorelinesIn a study, we see that plastic microparticles are contaminating the world’s shorelines and that much of the pollution appears to come from fibers from washing polyester clothes. The same study also took samples from ocean beaches. Five samples were taken from each of 18 different shorelines worldwide, for a total of 90 samples of size 250 mL. The mean number of plastic microparticles found per 250 mL of sediment was 18.3 with a standard deviation of 8.2. (a) Find a 95% confidence interval for the mean number of polyester microfibers per 250 mL of beach sediment.Round your answers to two decimal places.The 95% confidence interval is to .

A 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.

Using a TI-84 Plus calculator, I need to know the step by step process to calculate these. I don’t need these just written out on paper, but I also need to be shown the every move made into the calculator. Like, ‘STAT’ then ‘TESTS’ then ‘2: T-Test’, and so on.
Question 3 of 15> It is believed that the height of the taller parent is related to the height of the tallest child. To test this, a random sample of 5 families were selected and the height of the tallest parent, to the nearest inch, and the height of the tallest adult child, to the nearest inch, were recorded. The results of the sample are listed in the table. 61 63 68 70 72 74 Height of tallest parent Height of tallest child 62 63 71 72 68 76 Which of the following is the value of the correlation between the height of the tallest parent and the height of the tallest adult child?

Data are collected in an experiment designed to in- vestigate the impact of different positions of the mother during ultrasound on fetal heart rate. Fetal heart rate is measured by ultrasound in beats per minute. The study includes 20 women who are as- signed to one position and have the fetal heart rate measured in that position. Each woman is between 28 weeks and 32 weeks gestation. The data are shown in Table 7–7. Is there a significant difference in mean fetal heart rates by position? Run the test at a 5% level of significance. back side sitting standing 140 141 144 147 144 143 145 145 146 145 147 148 141 144 148 149 139 136 144 145
