Question: Consider the following competing hypotheses and accompanying sample data. (You may find it useful to reference the appropriate table: z table or t table )

Consider the following competing hypotheses and accompanying sample data. (You may find it useful to reference the appropriate table: z table or t table) H₀: ₁ - ₂ = 7 H_A: ₁ - ₂ 7

x1x1 = 54	x2x2 = 40
s₁= 22.5	s₂= 16.2
n₁ = 24	n₂ = 19

Assume that the populations are normally distributed with equal variances. a-1. Calculate the value of the test statistic. (Round final answer to 3 decimal places.)
