Assume that you have a sample of n 1 equals 8 n1=8, with the sample mean Upper X overbar 1 equals 47 X1=47, and a sample standard deviation of Upper S 1 equals 4 comma S1=4, and you have an independent sample of n 2 equals 14 n2=14 from another population with a sample mean of Upper X overbar 2 equals 32 X2=32 and the sample standard deviation Upper S 2 equals 7. S2=7. Complete parts (a) through (d) below. a. What is the value of the pooled-variance t Subscript STAT tSTAT test statistic for testing Upper H 0 : mu 1 equals mu 2 H0:1=2? t Subscript STAT tSTAT equals = enter your response here (Round to two decimal places as needed.)
