Big Sweets candy company is testing one of its machines in the factory to make sure it is producing more than 96% high-quality candy (Ho: P = 0.96; Ha: p > 0.96; a = 0.05). The test results in a p-value of 0.12. However, the company is unaware that it is actually producing 98% high-quality candy. What MOST likely happens as a result of the testing? O The company rejects Ho, making a Type I error. O The company fails to reject Ho, making a Type I error. O The company rejects Ho, making a Type II error. O The company fails to reject Ho, making a Type II error. O The company rejects Ho correctly.

Question A physical therapist is interested in studying patients recovering from neck injuries. Let the proportion of neck injury patients who fully recover in less than 6 months be p. If the physical therapist wants to know if the proportion of neck injury patients who fully recover in less than 6 months is more than 75%, what are the null and alternative hypotheses?   Select the correct answer below:   H0: p=0.75; Ha: p>0.75   H0: p=0.75; Ha: p<0.75   H0: p>0.75; Ha: p=0.75   H0: μ=0.75; Ha: μ>0.75

Twins In 2009 a national vital statistics report indicatedthat about 3% of all births produced twins. Is the rateof twin births the same among very young mothers?Data from a large city hospital found that only 7 sets oftwins were born to 469 teenage girls. Test an appropriatehypothesis and state your conclusion. Be sure theappropriate assumptions and conditions are satisfiedbefore you proceed.

Scenario: 200 people were asked, “Who is your favorite superhero?” Below are the data.  Test the null hypothesis that the population frequencies for each category are equal.  α= .05. Iron Man Black Panther Wonder Woman Spiderman fo = 40 fo = 60 fo =55 fo = 45 fe = fe = fe = fe =   What is the correct result based on the data?

State whether the standardized test statistict indicates that you should reject the null hypothesis. Explain. (a) t=2.242 (b) t= 0 (c) t=2.195 (d) t= -2.254 0. (a) For t 2.242, should you reject or fail to reject the null hypothesis? O A. Reject Ho, because t> 2.219. O B. Reject Ho, because t 2.219. O D. Fail to reject Ho, because t<2.219.

Life on Other Planets Forty-three percent of people believe that there is life on other planets in the universe. A scientist does not agree with this finding. He surveyed 120 randomly selected individuals and found  69 believed that there is life on other planets. At α=0.01, is there sufficient evidence to conclude that the percentage differs from 43% ? Use the  P -value method with tables.   :H0   ▼(Choose one) :H1  ▼(Choose one) This hypothesis test is a ▼(Choose one) test.           (b)Find the critical value(s). Round the answer to two decimal places. If there is more than one critical value, separate them with commas. Critical Value(s): (c)Compute the test value. Round the answer to at least two decimal places. z= (d)Make the decision.   (choose one) the null hypothesis   (e)Summarize the results.   There is ▼(Choose one) that the percentage of people who believe that there is life on other planets differs from  43% .
