Samuel Morse determined that the percentage of a's in the English language in the 1800s was 8%. A random sample of 600 letters from a current newspaper contained 60 a's. Using the 0.10 level of significance, test the hypothesis that the proportion of a's in this modern newspaper is 0.09.
The 2006 Statistical Abstract of the United States reports on a survey that asked a national sample of 80,000 American households about pet ownership. Suppose (for now) that one-third of all American households own a pet cat. This survey found that 32.8% of the households sampled owned a pet cat. Is this number a parameter or a statistic? Calculate the Z-score of this sample proportion (0.328).
The better-selling candies are often high in calories. Assume that the following data show the calorie content from samples of M&M’s, Kit Kat, and Milky Way II. Test for significant differences among the calorie content of these three candies. At a .05 level of significance, what is the p-value
A sport psychologist wanted to test the extent to which daily intake of fat in grams, and amount of exercise (in minutes) can predict health m=(measured using a Body mass index {BMI} scale in which higher scores indicate poorer health.

It is commonly thought that SUVs and vans are safer than cars. If an SUV and a car are in a collision, does the SUV sustain less damage and thus need a cheaper repair? We performed 7 sample crashes of SUVs at 10mph into the rear ends of stopped cars. See the table of normal data below. SUV into car SUV damage ($) Car damage ($) CRV into Civic 1721 1274 Rav4 into corolla 1434 2327 Tucson into Forte 850 3223 Tiguan into Golf 2329 2058 Patriot into Caliber 1415 3095 Escape into Focus 1470 3386 Rogue into Sentra 2884 4560 Would you be able to say that SUVs are safer since they need less repairs? Should I use: confidence intervals z-score A cause/correlation/regression or Chi-Squared hypothesis tests
A researcher expects that the number of people (18 years and older) who report binge drinking in the past month will be higher for Appleton WI residents as compared to the national rate, which is 25%. The researcher samples 100 residents from Appleton WI (age 18+) and finds that 36 of the 100 Appleton residents reported binge drinking in the past month. Using this data set answer the following questions: What is χ2obt? What is the df for this test? What is χ2CV? Based upon your answers to 1A and 1C, specify whether you would reject the null hypothesis or would fail to reject the null hypothesis. Then explain what could be concluded about binge drinking based upon this result. Report the result in APA format (you will need to use the correct symbols, spacing and italics).
A tax accountant would like to test the claim that the proportion of individuals who owe when filing their taxes is greater than 0.20. If the z− test statistic was calculated as z=1.94, does the tax accountant have enough evidence to reject the null hypothesis? Assume α=0.05.
The research examining the effects of preschool childcare has found that children who spent time in daycare perform better on math and language tests than children who stay home with their mothers. The results show that a sample of n = 25 children who attended daycare before starting school had an average score of M = 87 with SS = 1536 on a standardized math test for which the population mean is μ = 81. The population distribution is normal. Use α= .01 a. Is this sample sufficient to conclude that the children with a history of preschool daycare are significantly better from the general population? b. Compute the 95% confidence interval. show all work
The p-value for the above problem is < 0.0001. Which of the following is a correct conclusion? There is not enough evidence that all of the proportions of European football players who take magnesium in topical, pill, and powder form are the same as reported by the football agency. There is strong evidence that all of the proportions of European football players who take magnesium in topical, pill, and powder form are different than reported by the football agency. There is strong evidence that all of the proportions of European football players who take magnesium in topical, pill, and powder form are the same as reported by the football agency. There is strong evidence that at least one of the proportion of European football players who take magnesium in topical, pill, and powder form is different than reported by the football agency. There is not enough evidence that at least one of the proportion of European football players who take magnesium in topical, pill, and…

In a study examining overweight and obese college football players, Mathews and Wagner(2008) found that on average both offensive and defensive linemen exceeded the at-risk criterionfor body mass index (BMI). BMI is a ratio of body weight to height squared and is commonlyused to classify people as overweight or obese. Any value greater than 30 kg/m2 is considered tobe at risk. In the study, a sample of n = 17 offensive linemen averaged M = 34.4 with a standarddeviation of s = 4.0. A sample of n = 19 defensive linemen averaged M = 31.9 with s = 3.5a. Use a single-sample t test to determine whether the offensive linemen are significantly abovethe at-risk criterion for BMI. Use a one-tailed test with α = .01.b. Use a single-sample t test to determine whether the defensive linemen are significantly abovethe at-risk criterion for BMI. Use a one-tailed test with α = .01.c. Use an independent-measures t test to determine whether there is a significant differencebetween the offensive linemen…
Interpret the following statement regarding the statistical findings of a research study. “61% (n = 36) of recipients of the low-carbohydrate diet and 23% (n = 14) of recipients of the low-fat diet completed the study and lost greater than 10% of their initial body weight (P < 0.001).” Number of participants who completed the study and lost greater than 10% of their body weight: P-value: Does this p-value indicate a statistically-significant difference in the average weight loss between the two groups:
