An advertisement for a popular weight loss clinicsuggests that participants in its new diet program lose, on average, more than 10 pounds. A consumer activist decides to test the authenticity of the claim. She follows the progress of 18 women who recently joined the weight reduction program. She calculates the mean weight loss of these participants as 10.8 pounds with a standard deviation of 2.4 pounds.(You may find it useful to reference the appropriate table:z tableort table)

a.Set up the competing hypotheses to test the advertisement's claim.

multiple choice 1

• H₀:= 10;H_A: 10
• H₀: 10;H_A:< 10
• H₀: 10;H_A:> 10

b-1.Compute the value of the test statistic.(Round final answer to 3 decimal places.)

b-2.Find thep-value.

multiple choice 2

• p-value < 0.01
• 0.01 p-value < 0.025
• 0.025 p-value < 0.05
• 0.05 p-value < 0.10
• p-value 0.10

c.At the 5% significance level, what does the consumer activist conclude?
