Question

We want to verify if the colour of a car correlates with its top speed. We have taken the following sample:

	Black	Red	White	Total
under 110 mph	44	58	39	141
110 mph-140 mph	42	58	51	151
over 140 mph	34	37	23	94
Total	120	153	113	386

Compute the chi-squared statistic (not the corresponding probability from the table!) for this data and enter it to at least 1 decimal place.

Definition Definition Relationship between two independent variables. A correlation tells the degree to which variables move in relation to each other. When two sets of data are related to each other, there is a correlation between them.

From candy to jewelry to flowers, the average consumer was expected to spend $104.63 for Mother’s Day in 2005, according to a Democrat & Chronicle article. Local merchants thought this average was too high for their area. They contracted an agency to conduct a study. A random sample of 60 consumers was taken at a local shopping mall the Saturday before Mother’s Day and produced the sample mean amount of $94.27. If σ = $29.50, does the sample provide sufficient evidence to support the merchants’ claim at the 0.03 level of significance? 1.

Here are the data: Final grade in class: Prof Lavigne: 67,74,82,55 Monkey: 43,66,52,10 No professor: 97,87,86,78 We now want to figure out if the average final grade in each class is different from one another. What kind of analysis does this require?
