a) A travel TV hosts claim that backpackers age are varies and the distribution for the travel age is as follows: 20-29 years old (16%), 30-39 years old (40%), 40-49 years old (25%) and 50 and over (19%). To prove this, he asked 280 backpackers their age and Table 1 shows the result of the interview based on the age group. Table 1: Survey of the Backpackers' Age 20-29 years old 30-39 years old 40-49 years old Over 50 years old 60 100 80 40 Conduct the hypothesis testing with 95% confidence level to test the claim by the TV hosts. Note: Use notation as follows: pi = 20-29 years old travelers; p2 = 30-39 years old travelers; p3 = 40-49 years old travelers; P4 = 50 years old traveler. Given the hypothesis statement: Ho: Pi = 0.16, p2 =0.4, p3 =0.25, p3 =0.19 Hj: At least one of the p is different from the claimed value Calculate the x2 test value: 20-29 30-39 40-49 Over 50 Observed Frequency (0) 60 100 80 40 Expected Frequency (E)* 70 53 x? *For Expected Frequency (E), answer in round number Thus, the x'test = Get the critical value (x?cv): Critical value (x²cv)=x² State the conclusion of your test: Based on the xtest and x?cv, we the null hypothesis.
