One study examined the effect of Jumping on the bone density of gro ng rats There were three treatments a control with no Jumping, a la un p condition the ump height was 3。co timeters and a high-Jump condition (60 centimeters). After 8 weeks of 10 jumps per day, 5 days per week, the bone density of the rats (expressed in mg/cm3 ) was measured. Here are the data. data15 dat (a) Make a table giving the sample size, mean, and standard deviation for each group of rats. Consider whether or not it is reasonable to pool the varlances.(Round your answers for x, 5, and r to one decimal place.) GroupT (b) Run the ana sis of variance. Report the F statistic with its degrees of freedom and-value wat do you co dude?
