MATH 110 MODULE 4 EXAM 2023/2024 QUESTIONS AND ANSWERS- PORTAGE LEARNING Module 4 Exam Exam Page 1 A factory has eight safety systems. During an emergency, the probability of any one of the safety systems failing is .08. What is the probability that six or more safety systems will fail during an emergency? f(x) = ( (n!) / (x!(n-x)!) ) x ( (p^x) x ((1-p)^n-x)) ) n = 8 x = 6, 7, 8 (number of failures) p = 0.08 6 failures: n = 8 x = 6 p = 0.8MATH 110 MODULE 4 EXAM 2023/2024 QUESTI...

Portage Learning Math 110 Module 5 Exam 1. Suppose that you take a sample of size 20 from a population that is not normally distributed. Can the sampling distribution of x̄ be approximated by a normal probability distribution? No because the sample has to be at least 30 to use sampling distribution of x̄ or be normally distributed. 1b. Suppose that you take a sample of size 50 from a population that is not normally distributed. Can the sampling distribution of x̄ be approximated b...

Portage Learning Math 110 Module 6 Exam 1. A new drug for migraine headaches has been introduced to the market. You would like to know if migraine patients prefer the old drug or the new drug. So, you sample 190 patients that have used both drugs and you find that 52% of the sampled patients prefer the new drug, 48% of the patients prefer the old drug. Find the 90% confidence limit for the proportion of all patients that prefer the new drug. Can you be 90% confident that a majority of all th...

Portage Learning Math 110 Module 8 Exam Suppose we have independent random samples of size n1 = 420 and n2 = 510. The proportions of success in the two samples are p1= .38 and p2 = .43.

Portage Learning Math 110 Module 9 Exam Exam Page 1 1. Suppose you have 45 data points and you calculate the sample correlation coefficient and find that r = .32. Can you be 95% confident that a linear relation exists between the variables? If so, is the relation positive or negative? Justify you answer. Note that for n=45 and 95% we get a value from the chart of .29396. The absolute of r is |r|=.32, which is above .29396. So a positive linear relation exists.Portage Learning Math 110 Modu...

Portage Learning Math 110 Module 10 Exam 1 Find the value of X2 for 17 degrees of freedom and an area of .005 in the right tail of the chi-square distribution. Look across the top of the chi-square distribution table for .005, then look down the left column for 17. These two meet at X2 =35.718. 2. Find the value of X2 for 10 degrees of freedom and an area of .005 in the left tail of the chi-square distribution. Since the chi-square distribution table gives the area in the right tail...
