To compare customer satisfaction levels of two competing internet service provider companies, 174customers of Company 1 and 355 customers of Company 2 were randomly selected and asked to ratetheir internet service provider companies on a five-point scale, with 1 being least satisfied and 5 mostsatisfied. The survey results are summarized in the following table: Company 1 Company 2 n1 = 174 n2 = 355 Xi = 3.51 X2 = 3.24 S1 = 0.51 S2 = 0.52 4.1 Test at the 1% level of significance whether there is sufficient evidence toconclude that Company 1 has a higher mean satisfaction rating than does Company 2. (Ensure you use the following steps: Null hypothesis, Alternativehypothesis, Test statistic, Critical value, Decision with reason, Interpretation 4.2 Calculate the corresponding p-value 4.3 Interpret the p-value (not a generalized definition from text book)
