Using the unemployment data provided, investigate the association between the male unemployment rate in 2007 and 2010 for a sample of 52 countries. Complete parts a through d.
a) Find a regression model predicting the 2010 rate from the 2007 rate for the sample of 52 countries. State in simple language what the model says.
2010 Index=+x 2007 index (Round to two decimal places as needed.)
State in simple language what the model says. Select the correct choice below and fill in the answer box to complete your choice.(Round to two decimal places as needed.)
The 2010 rate increased by per year.
For each 1% increase in the 2010 rate, the 2007 rate increased by
For each 1% increase in the 2007 rate, the 2010 rate increased by
The 2007 rate increased by per year.
b) Determine the test statistic.
T= (Round to two decimal places as needed.)
Determine the P-value.
P=(Round to three decimal places asneeded.)
Make a conclusion.
Since the P-value is (1) the significance level, α, (2) the null hypothesis. The association (3) significant.
c) What percentage of the variability in the 2010 Index is accounted for by the regression model?
The regression model accounts for nothing % of the variability in the 2010 Index.
(Round to one decimal place as needed.)

Marco is studying a type of mold that grows at a fast rate. he created the function f(x) = 345(1.30)x to model the number of mold spores per week. what does the 1.30 represent? how many mold spores are there after 4 weeks? round your answer to the nearest whole number. 1.30 represents the number of mold spores marco had at the beginning of the study; 985 mold spores 1.30 represents the number of mold spores grown in a given week; 448 mold spores 1.30 represents the 30% rate of weekly growth; 345 mold spores 1.30 represents the 30% rate of weekly growth; 985 mold spores
