A researcher is interested in estimating the mean value for a population She takes a random sample of 17 items and computes a sample mean of 224 and a \'ample standard deviation of 32 She decides to construct a 98% confidence interval to estimate the The degrees of freedom associated with this problem are -. 18 17 16 15 20

Solution

degrees of freedom is n-1=17-1=16

So the correct option is (c)
