dam believes that the average round-trip fare from Sydney to Paris from Qantas (Population 1) is higher than that offered by Air France (Population 2). He collects samples of data from the Qantas and Air France websites for various departure and return dates. Assuming equal variances in the prices, is there evidence to support his claim at the 1% level of significance?Useworksheet Bof the Excel Exam data file to answer this question.

The mean price for Qantas is given by

A)1817.30

B) 5920.76

C) 8018.67

D) 1809.22

The variance of prices from Air France is given by

A)1809.20

B) 8018.67

C) 1817.30

D) 3822.84

The null and alternative hypotheses are

A) H0: 1 - 2 = 0; H1: 1 - 2 ? 0

B) H0: 1 - 2 ? 0; H1: 1 - 2

C) H0: 1 - 2 > 0; H1: 1 - 2 ? 0

D) H0: 1 - 2 ? 0; H1: 1 - 2 > 0

Assuming equal variances, the decision rule at the 1% level of significance is

A) reject H0 if t > 2.55

B) reject H0 if Z > 2.55

C) reject H0 if t 2.55

D) reject H0 if t

The pooled variance is

A)1809.20

B) 8018.68

C) 5920.76

D) 3822.84

The calculated test statistic is

A)-1.33

B) 1.33

C) 0.24

D) -2.55

Thep-value for this test is

A)0.24

B) 0.41

C) 0.05

D) 0.01

The conclusion to the hypothesis test is

A)reject H0 and hence conclude that the average roundtrip fare from Sydney to Paris from Air France is greater than that from Qantas.

B) do not reject H0 and hence conclude that the average roundtrip fare from Sydney to Paris from Qantas is not higher than that from Air France.

C) reject H0 and hence conclude that the average roundtrip fare from Sydney to Paris from Qantas is greater than that from Air France.

D) do not reject H0 and hence conclude that the average roundtrip fare from Sydney to Paris from Qantas is higher than that from Air France.
