An advertisement for a popular weight-loss clinic suggests 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. Which of the following are appropriate hypotheses to test the advertisement’s claim?
The consumer activist wants to prove that participants of the new diet program, on average, lose more than 10 pounds. Then the null hypothesis would be
H0: μ= 10
The null hypothesis indicates that a population parameter (in this case, mu represents the population mean) is equal to a hypothetical value. And the alternative hypothesis is what she expects to prove:
First you add up the red and black so see how many she has total. 45 + 60= 105 then if you need to find the probability of the red candies you put 45/ 105 then you can simplify it so it would be 8/21
