Two orchestra's are auditioning for a spot in the finals. Their performances were rated and received the following scores:
Orchestra 1: n1 = 31, x1= 78, s1 =10..........
Orchestra 2: n2 = 30, x2 = 72, S2 = 14.
What is the perfomance statistics, p value and is there sufficient evidence to justify the rejection of H0 at the significance level of 0.05?
