What would be the appropriate inferential statistic to evaluate the relationship between: • 'Generation' [Baby Boom (1946-1964), Generation X (1965-1980), Millennials (1981-1996)] • 'Household Income' (in US $) median and interquartile range means comparison (t or ANOVA) correlation coefficient (r) chi-square (x2) mean and standard deviation frequency and percentage
Suppose we want to test the hypothesis that mothers with low socioeconomic status (SES) deliver babies whose birth weights are different from normal. To test this hypothesis, a random sample of 100 birth weights is selected from a list of full-term babies of SES mothers. The mean birth weight is found to be 115 oz. Suppose the average birth weight of all babies (based on nationwide surveys of millions of deliveries) is known to be 120 oz with = 24 oz. Set = .05 Assume all conditions are met, what is the p-value of their test? Give your answer to 4 decimal places.
What proportion of variance in husband height is predictable from wife height? What proportion of variance in wife height is predictable from husband height?
If a distribution has a mean of 46 and a standard deviation of 1, what value would be -2 standard deviations from the mean?
A study of B.A. (Hons.) Economics examination results of 1000 students in 1990 gave the mean теаn grade as 78 and the standard deviation as 8.0. A similar study in 1995 revealed the mean grade of the group as 80 and the standard deviation as 7-6. In which year was there the greater (i) absolute dispersion, (ii) relative dispersion ? What can we say about the average performance of the students over time?
When using analysis of variance , the calculated F statistic will decrease as A) the variability among the groups decreases relative to the variability within the groups.B) the total variability increases.C) the total variability decreases.D) the variability among the groups increases relative to the variability within the groups.
Avalanches can be a real problem for travelers in the western United States and Canada. Slab avalanches studied in Canada had an average thickness of u = 67 cm. A sample of 31 avalanches in the U.S. gave a sample mean of = 63.0 cm. It is known that o = 10.3 cm for this type of data. Use a 0.03 level of significance to test the claim that the mean slab thickness of avalanches in the United States is different from that in Canada. Use the P-Value Approach. What is the P-Value for this problem? O 0.0154 0.0150 0.0300 0.0308
The chart to the right shows that a professor's grading distribution is bell shaped, or normally shaped. The mean of the distribution is 74 and the standard deviation is 9. Using a Continuous Variable Normal Bell Distribution Model, calculate the minimum test score needed to score in the top 5% of the class. Complete your work in the worksheet by listing the formula inputs, labels for the formula inputs and make your calculations with formulas. This test problem is similar to what you studied in video # 32, 33 and 34 and homework problems # 17, 21 and 23. Relative Frequency Frequency Professor looks at all test score for a particular test (this is population data), and observes: 0.5 0.45 0.4 0.35 0.3 0.25 0.2 0.15 0.1 0.05 0 Mean = 74 Median = 74 Mode = 73 SD=9 0 0 0 up to 10 up 10 to 20 0 20 up to 30 0 30 up to 40 2 40 up to 50 29 50 up to 60 X = Score 112 60 up to 70 225 70 up to 80 111 80 up to 90 21 2 90 up 100 up to 100 to 110

The daily milk production of a herd of Guernsey cows has a Normal distribution with mean 73 pounds and standard deviation 15 That is, the milk production is distributed ?(70,13) for these cows. What percent of Guernsey cows have milk production less than 60 pounds? What percent of Guernsey cows have milk production between 60 and 90 pounds? What milk production amount describes the lowest producing 30% of Guernsey cows?
The patient recovery time from a surgical procedure is normally distributed with a mean of 5.2 days and population standard deviation of 1.6 days. (a) What is the probability of spending more than two days in recovery after a surgical procedure? (c) What is the 90th percentile for recovery time after a surgical procedure? How do I calculate this in my calculator/ what is the formula I can use without it
