Use the given information to solve the following problems. 1) In the lab you have an unknown compound containing only the elements C,H,Cl, and O. Combustion analysis of a 40.10 g sample of the compound yields 58.57 g of Co2 and 14.98 g of H2O. A different sample of the same compound with a mass of 75.00 g is found to contain 22.06 g of Cl through gravimetric analysis. Determine the mass percent of each element present in the unknown...

The mean life of a battery used in a digital clock is 305 days. The lives of the batteries follow a normal distribution. The battery was recently modified to last longer. A sample of 20 of the modified batteries had a mean life of 308 days with a standard deviation of 12 days. A hypothesis test is undertaken to determine whether the modification increased the battery life. What is the value of the test statistic for the hypothesis test? In...
