Are there less children diagnosed with Autism Spectrum Disorder (ASD) in states that have larger urban
areas over states that are mostly rural?
Assume data were collected from a fairly urban state and they found 222 eight-year olds diagnosed with
ASD out of 19823 eight-year olds evaluated.
Assume data were then collected for a fairly rural state and they found 58 eight-year olds diagnosed with
ASD out of 2493 eight-year olds evaluated.
Is there enough evidence to show that the proportion of children diagnosed with ASD in the fairly urban
state is lower than the proportion in the fairly rural state?
a.) Test at the 3% level
b.) Compute a 97% confidence interval for the difference in proportions.
Use the following steps for the hypothesis test.
For the confidence interval you do not need to do all the steps since you did some of them already in
hypothesis test.
Part a.) HYPOTHESIS TEST

A study of tipping behaviours examined the relationship between the colour of the shirt worn by the server
and whether or not the customer left a tip.
Group 1: In a random sample of 66 customers served by a server wearing a red shirt, 40 left a tip.
Group 2: In a random sample of 354 customers served by a server wearing a non-red shirt, 186 left a tip.
At the 5% level of significance, is there a difference in tip leaving between red-shirted servers and non-
red-shirted servers?
Note: Be sure to use at least five decimal places in all intermediate calculations.

In individuals with this syndrome, cardiovascular disease is a common cause of death in the teenage years. A clinical study examined the effect of treatment with the drug lonafarnib on a number of physiological outcomes. The researchers measured the pulse wave velocity (PWV) of 18 children diagnosed with progeria and recruited worldwide. The study reports that the mean PWV of 18 children diagnosed with progeria is 12.44 m/s, and the standard deviation is 3.638 m/s. Assuming that PWV is normally distributed, is there significant evidence that the mean PWV of children with progeria is abnormally high (i.e. greater than 6.6 m/s)? Let μ (pronounced as "mu") be the true mean PWV of children with progeria. 1. What are the two competing hypotheses? [Select] 2. What is the test statistic? [Select] 3. What is the p value?
