You want to run a hypothesis test on the proportion of a phenomenon occurring. You make the following choices: Significance level: 5% Null Hypothesis: p >= 0.6 Alternate Hypothesis: p < 0.6 A sample is then taken with the following properties: A sample size of 120 A sample proportion of 0.54 Run a hypothesis test and either reject or do not reject the null hypothesis.
This is the step1, so step 2 and step 3 and Step 4 must be answered. (Step 2: Test Statistic -Pearson's r correlation coefficient AND Step 3: Critical Values, and Step 4: Solve For the test stat) so based it from the photo. The table shows the number of hours spend by 30 students in studing and their test scores. Solve for the Pearson’s r and interpret the results. Use 5% significance level. Step 1: Null and Alternative Hypothesis Ho: r = 0; There is no significant relationship between the number of hours spent studying and the students test scores. Ha: r ≠ 0; There is a significant relationship between the number of hours spent studying and the students test scores. Step 2: Test Statistic -Pearson's r correlation coefficient Step 3: Critical Values, Step 4: Solve For the test stat PLEASE SHOW ME COMPLETE SOLUTIONS AND CORRECT ANSWERS THANK YOU!!

Is the alternative hypothesis supported? z=3.5 for H₁: μ=124.5 kilograms and H₂: μ# 124.5 kilograms The P-value is (Round to four decimal places as needed.) Determine whether the alternative hypothesis is supported at a 0.05 significance level. O A. The P-value is more than the significance level. Do not reject Ho. The alternative hypothesis is not supported. OB. The P-value is more than the significance level. Reject Ho. The alternative hypothesis is supported. OC. The P-value is less than or equal to the significance level. Reject Ho. The alternative hypothesis is supported. O D. The P-value is less than or equal to the significance level. Do not reject Ho. The alternative hypothesis is not supported.
A Two-Sample Hypothesis Test The principal at a local high school claims that the proportion of high school males taking AP statistics is the same as the proportion of high school females taking statistics. Upon surveying 30 males and 28 females. The principal found that 6 males and 7 females are taking AP statistics. Although the proportions of these two populations are close, can the principal state that they are, in fact, statistically the same? (ASsume a 5% level of significance.)

Question Help v A candy company says that the colors of its candies are 15% yellow, 14% red, 21% orange, 23% blue, 16% green and 11% brown. In a randomly selected bag of the candies, there were 28 yellow, 21 red, 10 orange, 10 blue, 5 green, 19 brown. Is this sample consistent with the company's advertised proportions? Test an appropriate hypothesis and state your conclusion. Complete parts a through g below. a) If the company's candies are packaged in the advertised proportions, how many of each color should have been expected in the bag of candies Red (Type integers or decimals rounded to two decimal places as needed.)
