Suppose that the proportion of all American adults that fit the medical definition of being obese is 0.23. A large medical clinic would like to determine if the proportion of their patients that are obese is higher than that of all American adults. The clinic takes a simple random sample of 30 of their patients and finds that 9 patients in the sample are obese. The researchers created the following simulated null distribution with 1000 trials using the One Proportion applet: Distribution of Count in Group1 150 100 Frequency 50 . 10 12 14 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 Counts 4 12 51 81 145 174 175 122 109 73 29 19 4 1 1 What is the appropriate label for the x-axis of the randomization distribution plot? Proportion of obese patients in a sample of 30 patients assuming the true proportion of obese patients is greater than 0.23 Proportion of obese patients in a sample of 30 patients assuming the true proportion of obese patients is equal to 0.23 Number of obese patients in a sample of 30 patients assuming the true proportion of obese patients is greater than 0.23 Number of obese patients in a sample of 30 patients assuming the true proportion of obese patients is equal to 0.23Suppose that the proportion of all American adults that fit the medical definition of being obese is 0.23.

Increase Decrease Remain the same
