document.write( "Question 1165764: A physician claims that joggers' maximal volume oxygen uptake is greater than the average of all adults. A sample of 15 joggers has a mean of 43.6 milliliters per kilogram (ml/kg) and a standard deviation of 6 ml/kg. If the average of all adults is 36.7 ml/kg, is there enough evidence to support the physician's claim at = 0.05?\r

This is a one-way t-test
\n" ); document.write( "test stat is a t(0.975, df=14)= (xbar-mean)/s/sqrt(n)\r
\n" ); document.write( "\n" ); document.write( "Ho: means are the same or the joggers are less
\n" ); document.write( "Ha: Joggers are more
\n" ); document.write( "critical value t > 1.761\r
\n" ); document.write( "\n" ); document.write( "t=(43.6-36.7)/6/sqrt(15)
