Suppose you have selected a random sample ofn=6measurements from a normal distribution. Compare the standard normalvalues with the correspondingvalues if you were forming the following confidence intervals.

(a )98% confidence interval

z=

t=

(b)95% confidence interval

z=

t=-----------------------------

(c)80% confidence interval

z=----------------------------

t=----------------------------

Note:Your z-values should be given in two decimal places and your t-values in three decimal places. Both should be the positive values.
