A method currently used by doctors to screen women for possible breast cancer fails to detect cancer in 15% of the women who actually have the disease. A new method has been developed that researchers hope will be able to detect cancer more accurately. A random sample of 80 women known to have breast cancer was screened using the new method. Of these, the new method failed to detect cancer in 9. Conduct the hypothesis test to see if the percentage of failed detection has decreased at the 0.05 alpha level. Z0 = Round to the hundredth place. P-Value = Round to the thousandth place. Decision = (Either write Reject or Don't Reject).

700 doctors went through extra training compared to 1200 doctors who did not. Of the doctors who went through extra training, 125 of them majored in psychology. Of the 1200 doctors who did not do extra training, 174 of them majored in psychology. Perform a hypothesis test to see if there is a statistically significant evidence that the proportion of doctors who went through extra training is significantly greater than the proportion of doctors who did not. Perform the test at the alpha = .5 level. What is the p value and conclusion of this test?
A farmer wants to test the effectiveness of a pest control method in allowing strawberry blooms to yield marketable strawberries. Out of a random sample of 105 blooms, 77 yield marketable strawberries. Test that more than two-thirds of all blooms grown with this pest control method end up as marketable strawberries. Alpha = 0.02
The percentage of 12- to 17-year-olds who reported talking at least once in the past year with their parents about the dangers of drug, tobacco, or alcohol is 60% nationally. A state youth council believes this proportion is higher in their state, where there has been an intense media campaign about this issue. A survey of randomly chosen students from across the state shows 1032 of 1642 students reporting they are having these conversations with their parents. Use an alpha = .5
A card company claims that 80% of all American college students send a card to their mother on Mother's Day. You take a random sample of 125 American college students and find that 70% of them sent a card to their mother on Mother's Day. At a .05 alpha level, can you prove or disprove the card company's claim? Show all work.
FIV (feline immunodeficiency virus) attacks a cat's immune system causing FAIDS (feline acquired immunodeficiency syndrome). It is estimated that between 2 and 25 percent of the global domestic cat population is infected with the virus. FIV is primarily transmitted from cat to cat through biting. A one-step immunochromatographic (IC) test has been developed for the detection of FIV antibodies. It is estimated that 94.7% of cats with FIV test positive and 96.1% of cats without FIV test negative using this test. Assume that 5% of the local cat population is actually infected with FIV. Use this information to answer the following: (a) For a population of 100 000 cats: (i) how many are estimated to be infected with FIV? (ii) how many of the cats in (a)(i) will test positive? (b) Use your answers from (a) to help construct a 2 × 2 table of counts displaying the results for this sample. Complete the table. Estimate the proportion of local cats that would test negative for FIV but actually be…

According to the USDA, 46.2% of males between 20 and 39 years old consume the minimum daily requirement of calcium. After an aggressive “Got Milk?” campaign, the USDA conducts a survey of 48 randomly selected males between the ages of 20 and 39 and finds that 32 of them consume the recommended daily allowance of calcium. At the alpha=0.10 level, is there evidence to conclude that the percentage of males between the ages of 20 and 39 who consume the minimum recommended daily allowance of calcium has increased?
In a survey by Bea et.al., it was found that 218 of 1,062 urban residents had a history of allergic disorder while 728 of 1,000 rural dwellers had no history of such disorder whatsoever. Using an alpha level of 0.10, determine if the proportion of urban and rural residents with a history of allergic disorder are different. Use the seven steps of hypothesis testing.
The drug AZT was the first drug that seemed effective in delaying the onset of AIIDS in people infected with HIV. Evidence for AZT's effectiveness came from a large randomized comparative experiment. The subjects were 1300 HIV-positive volunteers who had not yet developed AIIDS. The double-blind study assigned 435 of the subjects at random to take 500 milligrams of AZT each day and another 435 to take a placebo. At the end of the study, 38 of the placebo subjects and 17 of the AZT subjects had developed AIDS. (a) Calculate and interpret the odds ratio, OR, and the relative risk, RR, for the AZT group compared with the placebo group. (Enter your answers rounded to four decimal places.) RR = OR = How do the values for OR and RR compare? O The OR value is much larger than the RR value which must imply the risk of getting AIDS while not using AZT is much higher. Both values are very easy to interpret since they are quite intuitive. O The OR value is somewhat similar to the RR value but is…
A researcher randomly selected a sample of n = 500 individuals from a population with µ = 120 and administered an experimental treatment to the sample. What the researcher should expect if the treatment has no significant effect?
A humane society claims that less than 67% of US households own a pet. In a random sample of 600 U.S households, 390 say they own a pet. At alpha= 0.10, is there enough evidence to support the society's claim?
Prior to an intensive TV advertising campaign, the producers of Nike athletic shoes find that 29 of a random sample of 200 upper-income adults are aware of their new leisure shoe line. A second random sample of 300 such adults is taken after the campaign. Now 96 of the persons sampled can identify the new line. Is the increase in the proportion of upper income adults showing brand awareness significant? Test the claim using alpha = .05.
