Life on Other Planets Forty-six percent of people believe that there is life on other planets in the universe. A scientist does not agree with this finding. He surveyed 100 randomly selected individuals and found 40 believed that there is life on other planets. At α=0.01, is there sufficient evidence to conclude that the percentage differs from 46% ? Use the P -value method with tables.   :H0   ▼(Choose one) :H1  ▼(Choose one) This hypothesis test is a ▼(Choose one) test.           Compute the test value. Always round z  score values to two decimal places. z= Find the P -value. Round the answer to four decimal places.

Use technology to find the​ P-value for the hypothesis test described below. The claim is that for 12 AM body​ temperatures, the mean is μ > 98.6 °F. The sample size is n = 3 and the test statistic is t = 1.234.

College students and STDs: A recent report estimated that 25% of all college students in the United States have a sexually transmitted disease (STD). Due to the demographics of the community, the director of the campus health center believes that the proportion of students who have a STD is higher at his college. He tests H0: p = 0.25 versus Ha: p > 0.25. The campus health center staff select a random sample of 150 students and determine that 43 have been diagnosed with a STD. Conduct a hypothesis test to address the director’s hypothesis. Use a 5% significance level to make your decision. Use the applet to determine the P‑value. Click here to open the applet. Which of the following is an appropriate conclusion based on the results?  The data provides strong evidence that the proportion of students at his college who have a STD is more than 25%.  The data suggests that the proportion of students at his college who have a STD is 29%.  Of the students surveyed at his college, 29%…

Effect size is the amount of statistical importance a particular finding has in psychological practice. the power of a study divided by the sample size. the sample size multiplied by 1 – beta.  the degree to which an experimental manipulation separates two populations.

The proportion of people who live after fighting cancer is 0.75. Suppose there is a new therapy that is used to increase the survival rate. Use the parameter p to represent the population portion of people who survive after fighting cancer. For a hypothesis test of the therapy’s effectiveness, researchers use a null hypothesis of p = 0.75. Pick the correct alternative hypothesis.  1. p > 0.75        2. p < 0.75          3. p 6= 0.75
