A friend of yours tells you that they heard that 65% of all college athletes end up losing a finger or toe in their college athletic career. You're highly skeptical of this, but your not sure if that percentage is an over exageration or an under exageration. You survey 101 former student-athletes and find that 60 of them lost a digit during their college athletic career. Is this enough evidence to conclude that the true percentage of student-athletes that lose a digit during their collegiate career is really different from 65%?
The national center for educational statistics reported that in 2008-2009, 178,564 master's degrees in education were awarded in the United States, and that this represented 27% of all master's degrees awarded. How many master's degrees were awarded in 2008-2009?
Sleep apnea is a condition in which the sufferers stop breathing momentarily while they are asleep. This condition results in lack of sleep and extreme fatigue during waking hours. A current estimate is that 11.911.9 million out of the 312.7312.7 million Americans suffer from sleep apnea, or approximately 3.8%3.8%. A safety commission is concerned about the percentage of commercial truck drivers who suffer from sleep apnea. They do not have any reason to believe that it would be higher or lower than the population’s percentage. To test the claim that the percentage of commercial truck drivers who suffer from sleep apnea is not 3.8%3.8%, a simple random sample of 347347 commercial truck drivers is examined by a medical expert, who concludes that 66 suffer from sleep apnea. Does this evidence support the claim that the percentage of commercial truck drivers who suffer from sleep apnea is not 3.8%3.8%? Use a 0.020.02 level of significance. Step 3 of 4 : Find the p-value.

An article was published concerning the incidence of cardiac death attributable to earthquake in Los Angeles County on January 17, 1994. In the week before the earthquake there were an average of 15.6 cardiac deaths per day in Los Angeles County. On the day of the earthquake, there were 51 cardiac deaths. Among days with more than 10 admissions, what proportion fall on weekends?
Color blindness, or dyschromatopsia, is a form of genetic deficiency in color perception. The condition is much more prevalent among males than females, pointing to a genetic connection with the X chromosome. The frequency of dyschromatopsia in the Caucasian American male population is about 7%. However, it is thought that this proportion might be smaller among males of other ethnicities. We want to estimate the proportion of Asian American males who are color-blind. How large a sample size do we need in order to obtain a 95% confidence interval with a margin of error no greater than 5%, or 0.05? Use 0.5 for p̂.
Suppose that Ford vehicles make up 20% of the U.S. vehicles market. Suppose also that 8% of U.S. vehicles are Ford’s and trucks (that is, are Ford trucks). What proportion of Ford vehicles are a truck?
Based on a survey, more than 1 in 4 American children have cholesterol levels of 180 milligrams or higher.
In a 2018 Poll 447 out of 486 supported universal background checks for all gun sales in the U.S. In a similar poll from 2015, 276 of 321 interviewed supported universal background checks. Is this significant evidence that the percent of the population that supports universal background checks in the U.S. has decreased during this time?
According to an article in Newsweek, the natural ratio of girls to boys is 100:108. In Turkey, the birth ratio is 100: 118 (45.8% girls). Suppose you do not believe the reported figures of the percent of girls born in Turkey. You conduct a study. In this study, you count the number of girls and boys born in 140 randomly chosen recent births. There are 50 girls and 90 boys born of the 140. Based on your study, do you believe that the percent of girls born in Turkey is 45.8?
Sleep apnea is a condition in which the sufferers stop breathing momentarily while they are asleep. This condition results in lack of sleep and extreme fatigue during waking hours. A current estimate is that 16.3 million out of the 312.7 million Americans suffer from sleep apnea, or approximately 5.2%. A safety commission is concerned about the percentage of commercial truck drivers who suffer from sleep apnea. They do not have any reason to believe that it would be higher or lower than the population’s percentage. To test the claim that the percentage of commercial truck drivers who suffer from sleep apnea is not 5.2%, a simple random sample of 380380 commercial truck drivers is examined by a medical expert, who concludes that 29 suffer from sleep apnea. Does this evidence support the claim that the percentage of commercial truck drivers who suffer from sleep apnea is not 5.2%? Use a 0.01 level of significance.
