1.To test whether manufacturing cost can be predicted by labor cost, the best analysis is:

Select one:

a.Correlation

b.

ttest for dependent samples

c.ttest for independent samples

d.Simple linear regression

2.You pull data for the past 180 days on the variables of mobile advertising spending and number of website visits. You randomly sample data for10days and use Excel to compute statistics for the relationship between these two variables. You find thatr = 0.741, p = .005. You conclude that:

Select one:

a.

This is not enough information to make a decision about whether the analysis produces a good fitting model

b.This provides evidence that using mobile advertising spending to predict website visits produces a poorly fitting model

c.This provides evidence that using mobile advertising spending to predict website visits produces a good fitting model

d.This provides evidence that using mobile advertising spending to predict website visits produces a good fitting model, but the sample size is too small to determine statistical significance

3.To test whether manufacturing cost can be predicted by labor cost, preferably the data will be collected as:

Select one:

a.One numeric and one categorical variable

b.One numeric and one interval variable

c.Two categorical variables

d.Two numeric variables
