According to a guide, 45% of cell phone users have only one cell number, 35% have two numbers, 8% have three numbers, and 12% have four or more numbers. An independent survey of 958 randomly selected cell phone users found that 463 pay for only one number, 345 pay for two numbers, 103 pay for three numbers, and 47 pay for four or more numbers. Conduct a test to determine if the data from the independent survey contradict the percentages reported by the guide. Use α = 0.1. Determine the null and alternative hypotheses for this test. Choose the correct answer below. OA. Ho: P₁ P2 = P3 P4 Ha: P1 P2 P3 P4

Find the test statistic
Transcribed Image Text:According to a guide, 45% of cell phone users have only one cell number, 35% have two numbers, 8% have three numbers, and 12% have four or more numbers. An independent survey of 958
randomly selected cell phone users found that 463 pay for only one number, 345 pay for two numbers, 103 pay for three numbers, and 47 pay for four or more numbers. Conduct a test to
determine if the data from the independent survey contradict the percentages reported by the guide. Use α = 0.1.
Determine the null and alternative hypotheses for this test. Choose the correct answer below.
O A. Ho: P₁ P2 = P3 P4
Ha: P1
P2 P3 P4
O B. Ho: P1 P2 P3 P4
Ha: At least one of the multinomial probabilities equals its hypothesized value.
OC. Ho: P₁ = 45%, P2 = 35%, P3 = 8%, P4 = 12%
Ha: At least one of the multinomial probabilities does not equal its hypothesized value.
Now find the test statistic.
x² = (Round to two decimal places as needed.)
Determine the p-value.
