Given principal s9 000 interest rate 6% time 240 days (use ordinary interest) partial payments on 100th day, 53,200 on 180th day, s2,200 a. use the u. s. rule to solve for total interest cost. (use 360 days a year. do not round intermediate calculations. round your answer to the nearest cent.) total interest cost$ b. use the u. s. rule to solve for balances. (use 360 days a year. do not round intermediate calculations. round your answer to the nearest cent.) on 100th on 180th balance after the payment c. use the u. s. rule to solve for final payment. (use 360 days a year. do not round intermediate calculations. round your answer to the nearest cent.) final payment

The null and alternate hypotheses are: h0: μ1 ≤ μ2 h1: μ1 > μ2 a random sample of 22 items from the first population showed a mean of 113 and a standard deviation of 12. a sample of 16 items for the second population showed a mean of 99 and a standard deviation of 6. use the 0.01 significant level. find the degrees of freedom for unequal variance test. (round down your answer to the nearest whole number.) state the decision rule for 0.010 significance level. (round your answer to 3 decimal places.) compute the value of the test statistic. (round your answer to 3 decimal places.) what is your decision regarding the null hypothesis? use the 0.01 significance level.
