Suppose a linear regression equation was calculated to fit the relationship between the percentage of the adult population that is obese and the percentage who felt that they are very happy. These variables were measured on the population level of each of the United States and territories. How would you interpret the following estimated regression equation? Very happy (%) = 70.3 - 2.58 x Obese (%) Select one:
a. Slightly over 70% of the variation in the percent who are very happy is explained by obesity.
b. The variation in percent that are very happy that are explained by the model is 2.58.
c. For each percent increase in obesity, the percent of adults who are very happy decreased by 2.58, on average.

Conduct the test at the 0.05 level of significance whether the modification actually increased the life of the AAA battery. What was their decision rule?
Determine the value of the finite population correction factor if population size is 1000 and the sample size is 300? What is the smallest sample size for which finite population correction factor must be Used?
If the sample mean lifetime of the 100 batteries were 36.7 hours. would you find the manufacturer's claim plausible? Explain.
In other words, explain why, all else being equal, as sample size increases the likelihood of finding a statistically significant relationship increases.
