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?

A survey of contraceptive methods conducted by the National Center for Health Statistics in 1965 indicated that among 30-39 year old, married, nonpregnant women who practiced contraception 20% used some form of permanent contraception. The frequency of use of permanent contraception is suspected to have changed over the next 4 decades. To test this hypothesis, records were selected of 50 women subscribing to prepaid health plans in 2005 who were 30-39 year old, married, nonpregnant and practiced contraception. From these records 16 used some form of permanent contraception. Suppose we wish to test the hypothesis that a change has occurred in the true proportion of women who use permanent contraception without specifying the direction of that change. Suppose researchers are willing to commit the error of mistakenly rejecting the null hypothesis only 1% of the time. What is the significance level in this problem? Specify the null and alternative hypothesis Carry out the steps of the…
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. 1st statement: The sample proportion of urban residents with history of allergic disorder is 20.53% 2nd statement: The sample proportion of rural residents with history of allergic disorder is 72.80% a. both are true b. both are false c. first is teue, second is false d. first is false, second is true
Historically, the proportion of people who trade in their old car to a car dealer when purchasing a new car is 48%. Over the previous 6 months, in a sample of 115 new-car buyers, 46 have traded in their old car. The p-value for the test of whether the proportion of people who trade in their old cars to a car dealer has decreased is 0.0427. If we were to test this hypothesis at the 5% level of signficance, what can you conclude concerning the null hypothesis?

To determine whether the proportion of new car buyers that trade in their old car has this is sickly significantly decreased, what is the null and alternative hypothesis?
survey of a random sample of 1019 U.S. adults with invest-ments of $10,000 or more. Based on the survey data, it was estimated that 31% of investors manage their investments bydoing everything they possibly can online. But the authorsof the article also noted that there was a quite a difference between younger investors (ages 18 to 49) and older inves-tors (ages 50 and older). For younger investors, 43% said they do everything they possibly can online, while the per-centage for older investors was 23%. a. Use the given information to estimate P(O), P(O|Y), and P(O|F) where O 5 event that a randomly selected inves-tor does everything possible online, Y 5 event that a randomly selected investor is age 18 to 49, and F 5 eventthat a randomly selected investor is 50 years old or older.b. Suppose that 40% of investors are between the ages of 18 and 49. Use the probabilities from Part (a) and the esti-mate P(Y) 5 0.40 to construct a hypothetical 1000 table.Then use information in the table to…
A researcher wants to determine if exposure to subliminal (unconscious) images depicting older adults (80-95 years old) will influence the time it takes pedestrians to get across a busy intersection using a crosswalk. A random sample of sixty pedestrians are exposed to a set of subliminally presented positive images using a special electronic traffic signal before the signal prompts them to cross. From previous studies (using the same crosswalk and intersection), the experimenter knows that when no subliminal images are presented, the average time it takes the city’s population to cross is 30.5 seconds, with a standard deviation = 5.5 seconds.
