Victims of Violence A random survey of 70 women who were victims of violence found that 28 were attacked by relatives. A random survey of 48 men foundthat 7 were attacked by relatives. At a=0.05, can it be shown that the percentage of women who were attacked by relatives is different from the percentage ofmen who were attacked by relatives? Use P₁ for the proportion of women who were attacked by relatives.

Never Married People The percentage of males 18 years and older who have never married is 30.4 . For females the percentage is 23.6 . Looking at the records in a particular populous county, a random sample of 250 men showed that 73 had never married and 50 of 200 women had never married. At the 0.05 level of significance, is the proportion of men greater than the proportion of women? Use the P -value method and let p1 be the proportion of men.
Supposed that in the past, 10% of women in the Philippines have severe dysmenorrhea. Do we have enough reason to believe that the proportion of women having terrible cramps has decreased if, in a random barangay population of 1,256 women, 122 have severe enough cramping to interfere with their daily lives? Use a = 0.05
X10.2.21-T Twenty years ago, 56% of parents of children in high school felt it was a serious problem that high school students were not being taught enough math and science. A recent survey found that 247 of 700 parents of children in high school felt it was a serious problem that high school students were not being taught enough math and science. Do parents feel differently today than they did twenty years ago? Use the a=0.01 level of significance. Because npo (1- Po) = 172.5 > 10, the sample size is less than 5% of the population size, and the sample can be reasonably assumed to be random, the requirements for testing the hypothesis are satisfied. (Round to one decimal place as needed.) What are the null and alternative hypotheses? versus H,: Ho: (Type integers or decimals. Do not round.)

A jeep gets 53 highway miles per gallon. Howvever, an SUV believes gas mileage for their new line is much better. In order to test, they collect a random sample of 8 jeeps. The results of the 8 cars tested as as follows: 56, 51, 55, 54, 57, 48, 56, and 51. If you perform this test at a= .05 level, state the p-value and the conclusion of the test.
Can you solve for the p-value and is H0 rejected or not rejected?

A medical researcher tested a new treatment for poison ivy against the traditional ointment. He concluded that the new treatment is more effective. Explain what the P-value of 0.037 means in this context. Explain what the P-value of 0.037 means in this context. O A. There is a 3.7% difference between the effectiveness of the new treatment and the effectiveness of the traditional ointment. O B. If there is no difference in effectiveness, the chance of seeing an observed difference this large or larger is 3.7% by natural sampling variation. O C. If there is a difference in effectiveness, the chance of seeing an observed difference this large or larger is 3.7% by natural sampling variation. D. There is a 3.7% chance that the new treatment is effective.
