Solution A has a pH of 4.9 and solution B has a pH of 8.8. The acidity (pH) is a measure of the hydrogen ion concentration H + (measured in moles of hydrogen per liter) of solution. Acidity is modeled by $\mathrm{pH}=-{\log }_{10}\left[{\mathrm{H}}^{+}\right]$ . The hydrogen ion concentration of solution A is how many times the concentration of solution B.

A) The concentration of solution A is approximately 7,943 times the concentration of solution B.
B) The concentration of solution A is approximately 3.9 times the concentration of solution B.
C) The concentration of solution A is approximately 20 times the concentration of solution B.
D) The concentration of solution A is approximately 3.6 times the concentration of solution B.
E) The concentration of solution A is approximately 1.8 times the concentration of solution B.

Give an example of a one-tailed hypothesis that may be tested through a correlation.

According to the Empirical Rule,if the data form a bell shaped normal distribution,approximately ____________________ percent of the observations will be contained within 2 standard deviations around the mean.

The t-distribution allows the calculation of confidence intervals for means for small samples when the population variance is not known, regardless of the shape of the distribution in the population.

Jackson inherited $50,000 at the age of 42 and had a decision to make.He could deposit the money in a tax -deferred account that pays 3.375% compounded quarterly or he could deposit the money in a taxable account with the same interest rate and compounding period.Jackson's current tax bracket is 25%,which means he will have to pay taxes on the interest earned each year in the taxable account.How much money could Jackson have saved after 25 years if his decision was to deposit the inheritance into the taxable account?
