Question 3 of 10 < > -12 !!! Current Attempt in Progress Use a t-distribution and the given matched pair sample results to complete the test of the given hypotheses. Assume the results come from random samples, and if the sample sizes are small, assume the underlying distribution of the differences is relatively normal. Assume that differences are computed using $d = x_1 - x_2$. Test $H_0: \mu_d = 0$ vs $H_a: \mu_d \neq 0$ using the paired difference sample results $\bar{x}_d = 15.29, s_d = 13.2, n = 25$. Give the test statistic and the p-value. Round your answer for the test statistic to two decimal places and your answer for the p-value to three decimal places. test statistic = p-value = eTextbook and Media

A new state law took effect in January 2010 with a tax break for tax filers who contribute to college tuition accounts for their children. The percentage of tax payers who participated in this program since January 2010 can be modeled by the logistic function $P(t)$, where $t$ is the number of months since January 2010. If the percentage of tax payers increased from 20% to 50% since the new law took effect, which of these could be $P(t)$'s equation? $P(t) = \frac{20}{1+10e^{-0.4t}} + 30$ $P(t) = \frac{50}{1+10e^{-0.4t}}$ $P(t) = \frac{30}{1+10e^{-0.4t}} + 20$ $P(t) = \frac{50}{1+10e^{-0.4t}} + 20$

Monthly growth of rate of 0.25% o Note: • Taxes and Fees will be the same and in the same months as 2015 • G&A will be 20% of Revenue • COGS will be 50% of Revenue • Professional Costs will be the same until August 2016 when it will go up to 75,000 a month for the rest of the year (Including August) • Bad Debt Expense will be 1% of Cash Receipts. Answer the following questions: 1. If all assumptions are used, what would be the total Net Operating Cash Flow for 2016, round to nearest 2 decimals? 2. Do not assume facts from other questions. If all assumptions are used, except revenue increased only by 0.15% a month and COGS was 60% and Bad Debt was 1.8%, which month in 2016 would have positive cumulative Cash Flow? 3.
