An adminstrator working for Texas ISD wants to know whether or not the students ticketed for expired inspection stickers are likely to have prior auto violations on their record as do not. The data and SPSS output is as follows. Data point: Priors Observed: 25; Data Point: No Priors Observed: 61 Answer below: 1. State null and alternative hypothesis. H(o): The populationb distribution is uniform - an equal percentage of the population have prior ticket convictions as do not. H(alpha): The populationb distribution is not uniform - an unequal percentage of the population have prior ticket convictions as do not. 2. State level of significance or a "alpha". For this example use alpha = .05

The average age for licensed drivers in a county is 42.6, with a standard deviation of 12, and the distribution is approximately normal. A county police officer was interested in whether the average age of those receiving speeding tickets is less than the average age of the population who has a license. She obtained a sample of 16 drivers with speeding tickets. The average age for this sample was 34.4. Do all the steps of hypothesis testing using the 0.01 significance level.

A local group claims that the police issue at least 60 speeding tickets a day in their area. To prove their point, they randomly select two weeks. Their research yields the number of tickets issued from each day. The data are listed below. At alpha = 0.01, test the group's claim. 70 48 41 68 69 55 70 57 60 83 32 60 72 58 [Use the p-value approach to hypothesis testing.] Step1: Step 2: Step 3: Step 4: Step 5:
