Question 1:

Which of the following smtements about correlation is true? Choose the correct answer below. 0 A. We say that there is a positive correlation between x and y if the x-values increase as the corresponding yvalues decrease. O B. We say that there is a positive correlation between x and y if there is no distinct pattern in the scatterplot. O C. We say that there is a negative correlation between x and y if the x-values increase as the corresponding y-values increase. 0 D. We say that there is a positive correlation between x and y if the x-values increase as the corresponding yvalues increase. Suppose that in a random selection of 100 colored candies, 23% of them are blue. The candy company claims that the percentage of blue candies is equal to 30%. Use a 0.05 signicance level to test that claim. Identify the null and alternative hypotheses for this test. Choose the correct answer below. 0 A. Hozp=0.3 O B. Ho:p=0.3 O C. H0:p=0.3 o D. Hozpaeoa Identify the test statistic for this hypothesis test. The test statistic for this hypothesis test is (Round to two decimal places as needed.) Identify the Pvalue for this hypothesis test. The P-value for this hypothesis test is . (Round to three decimal places as needed.) Identify the conclusion for this hypothesis test. O A. Fail to reject Ho. There is not sufficient evidence to warrant rejection of the claim that the percentage of blue candies is equal to 30% O B. Fail to reject Ho. There is sufficient evidence to warrant rejection of the claim that the percentage of blue candies is equal to 30% O C. Reject Ho. There is not sufficient evidence to warrant rejection of the claim that the percentage of blue candies is equal to 30% O D. Reject Ho. There is sufficient evidence to warrant rejection of the claim that the percentage of blue candies is equal to 30%
