Stat Test 3 Study Guide The probability of a random outcome is a Unpredictable b 12 c the proportion of times the outcome would happen in a large number of repetitions If you assign the probability of 16 for rolling a 2 because the die is fair what type of probability are you using a Empirical probability b Theoretical c Personal probability d Random A probability of 1 can be interpreted to mean a The event has a 001 chance of happening b The event has a 1 chance of happening c The event has a 100 chance of happening Getting a 2 on the rst roll and a 2 on the second roll of a die are considered events a Disjoint bndependent c Codependent Two events are independent if a they share outcomes in common have an intersection b They share no outcomes in common no intersection c The occurrence of one event does not affect the occurrence of the other event d They are in different sample spaces Suppose the odds for getting a speeding ticket are 1 Find the probability of getting a speeding ticket a 1 b 12 c 2 d 0 One might use stimulation to compute a probability when a We do not know the probability model b The events are complete c We do not have random digits d There is a lot of time for computations The Central Limit theorem says that for a random sample the sample mean will a Be normally distributed b Be normally distributed with a large enough sample size c Be equal to the population mean d It is not a distribution 9 What is true about the sampling distribution of the sample proportion It is skewed Nothing is known about it It has a normal distribution It is not a distribution 10 the sampling distribution of a statistic describes the con dence interval is contained in the con dence interval c describes the possible values of a statistic and how often it takes those values all of the above 11 A 95 con dence interval says that the statistic will be contained in the interval 95 of the time the parameter will be within 95 of the statistic neither of the above both A and B A random sample of US adults were asked if a car is a necessity to life The resulting 95 con dence interval for the proportion who thinks a car is a necessity is 083 089 12 Choose the correct interpretation a We are 95 con dent that between 83 and 89 of US adults in the sample think having a car is a necessity b We are 95 certain that between 83 and 89 of US adults think having a car is a necessity c We are 95 con dent that between 83 and 89 of all US adults think having a car is a necessity 13 Using a bigger con dence level will result in the con dence interval being a the same width b wider c narrower d not enough info to say Researchers studied the effect of sunlight on multiple sclerosis MS They exposed rats to a protein which resulted in MS symptoms and then allowed one group exposure to sunlight and the other group no sunlight It was believed that exposure to sunlight would reduce MS symptoms 14 Find the Ho the null hypothesis MS symptoms are the same for sun and no sun groups MS symptoms more prevalent for sun groups MS symptoms less prevalent for sun group MS symptoms different for sun and no sun groups 15 The the Ha the alternative hypothesis MS symptoms the same for sun and no sun groups MS symptoms more prevalent for sun groups c MS symptoms less prevalent for sun group on cm 0 F7 goom on cm 0390 d MS symptoms different for sun and no sun groups 16 25 Their statistical test returned a Pvalue of 0001 Interpret this Pvalue a There is a 01 reduction in MS symptoms when exposed to suanht b There is a 01 chance MS symptoms are the same whether exposed to sun or not c There is a 01 chance of seeing this much reduction in MS symptoms if sunlight really does reduce MS symptoms d There is a 01 chance of seeing this much reduction in MS symptoms if MS symptoms are the same for sun and no sun exposure Answer Key CBCBCBBBC 123456189 CCCBACD OL73456
