A college administrator wants to know if there is a significant difference between sexual orientation and level of family support for students at their college. The administrator takes a random sample of students who identify as gay/lesbian, bisexual or heterosexual/straight. There were 22 students sampled in each category. A measure of family support is given with higher scores indicating more family support. The means are as follows:
Gay/lesbian
Bisexual

Despite smaller-ticket purchases, convenience stores can still be profitable because of the size of operation, volume of business, and the markup. A researcher is interested in estimating the average purchase amount for convenience stores in suburban Long Island. To do so, she randomly sampled 24 purchases from several convenience stores in suburban Long Island and tabulated the amounts to the nearest dollar (shown below). $9 $7 $1 $2 $14 $11 $7 $8 $6 $7 $3 $3 $2 $5 $4 $4 $1 $2 $3 $10 $8 $8 $6 $4 Assume that the population standard deviation is 3.23 and the population is normally distributed. Using the above data, a 90% confidence interval for the population average amount of purchases is 4.54 to 6.71 4.495 to 6.76 4.44 to 6.81 4.49 to 6.76 4.26 to 6.99arrow_forwardAn insurance company selected samples of clients under 18 years of age and over 18 and recorded the number of accidents they had in the previous year.

- A physician wanted to compare two types of pain relief. One is medication and the other is using pressure points. To test whether medication relieves pain faster, they have 10 migraine sufferers compare both types of pain relief and record their observations on a standardized scale. A coin flip was used to determine which type of headache relief each individual would try first. Results indicated that there was no difference in the two types of pain relief. Complete parts (a) through (f) below. (a)What type of experimental design is this? (b)What is the response variable in this study? (c)What is the factor that is set to predetermined levels? What is the treatment? (d)Identify the experimental units. (e)Why did the physician use a coin flip to determine which headache relief each individual would try first?

The researcher recruited n = 5 participants and asked them to solve a difficult puzzle in a short time period. She then asked each participant to rate how stressful the task was and how frustrated they were to solve the puzzle on a scale of 1 to 5. The data are below: X Stress Y Frustration 2 2 3 3 3 1 2 4 4 5 21. Assuming all choices would be equally likely to be chosen, what would be the expected frequency (fe) for all groups? 22.
