Answer item #2 only. Thanks Activity:Problem Solving.Read and analyze the given problem then answer the following questions.1. A random sample of n = 90 is taken from a normally distributed population with a mean of u = 80 and standarddeviation of o = 5. Given the sample mean and standard deviation of x = 77 and s = 3.3 respectively. Solve for teststatistic.Given:Solution:Ho =2. A student assistant administers an exam for the incoming grade 11 ABM students. Fifteen incoming grade 11 ABMstudents were selected randomly, and the results were as follows mean score of 90 with standard deviation of 10. Thepopulation parameters are u = 83 and o = 15.Given:Solution:Ho =n =x= Illustrative Example 1:Solve for the test statistic.The heart rates of 50 patients in an ICU have mean 95.3 beats/min and standard deviation 16.9 beats/min. Areheart rates from ICU patients unusual given normal heart rate has mean of 72 beats/min with a significance of 0.01?Given:Solution:- normal heart rate- number of patients beingsurveyed*The sample size of 50 patients is large enough forthe Central Limit Theorem to satisfy theassumption that the sampling distribution of meansHo = 72 beats/min.n= 50 patientsthe appropriate test statisticto use is z-test, since thedistribution is normal, wecan use s as an estimator ofo.- substitute all the give(95.3 -72)(16.9//50)is normal.- heart rate of 50 patients- therefore we will be usingx= 95.3beats/min.z = 9.75- test statistico = unknown* Central limit theorem states that for a sample which islarge enough the value of t – test is approximately equalto the value of z – test as the sample size increases. Inz-tests= 16.9 beats/min.- sample standard deviation- significance level *this willbe essential on our next topic.a = 0.01this case we can use s as an estimator of o.
