4. QUESTION To compare customer satisfaction levels of two competing internet service provider companies, 174 customers of Company 1 and 355 customers of Company 2 were randomly selected and asked to rate their internet service provider companies on a five-point scale, with 1 being least satisfied and 5 most satisfied. The survey results are summarized in the following table: Company 1 Company 2 n = 174 n2 = 355 x, = 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 to conclude that Company 1 has a higher mean satisfaction rating than does Company 2. (Ensure you use the following steps: Null hypothesis, Alternative hypothesis, Test statistic, Critical value, Decision with reason, Interpretation). 4.2 Calculate the corresponding p-value

To compare customer satisfaction levels of two competing internet service provider companies, 174
customers of Company 1 and 355 customers of Company 2 were randomly selected and asked to rate
their internet service provider companies on a five-point scale, with 1 being least satisfied and 5 most
satisfied. The survey results are summarized in the following table:
Company 1
Company 2
nį = 174
n2 = 355
ž = 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 to
conclude that Company 1 has a higher mean satisfaction rating than does
Company 2. (Ensure you use the following steps: Null hypothesis, Alternative
hypothesis, 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)
