Solve. Also, use n=40. It's not in the question. Thank you
The mean is 146 and the standard deviation is 35. A score of 41 is how many z-scores below the mean?
The police reported that the average driver exceeds the 50 miles per hour speed limit by more than 9 miles per hour on the busiest street in a small town. A sample of 63 randomly selected cars were clocked by airplane radar. The average speed was 57.5 miles per hour, and the standard deviation of the speeds was 4.17 miles per hour. Determine if the average speed is greater than what the police department reported. Which parameter(s) are you given? Mark all that apply. p μ σ none Which statistic(s) are you given? Mark all that apply. ¯x ˆp ˆq s x none What is the problem asking you to do? Estimate a parameter Test a given parameter
Determine the number of standard deviations from the mean (z-score). In the United States, the distribution of a male's height has a mean of 69 inches with a standard deviation of 3 inches. How many standard deviations from the mean is John Doe, who is 67 inches tall? Question 15 options: 0.67 standard deviations below the mean 0.33 standard deviations below the mean 2 standard deviations below the mean 1 standard deviation below the mean
n=16 mean number of television per household is 4 with a standard deviation of 1 television. using chebychev's theorem, detemine at least how many households have between 2 and 6 television.
Suppose a researcher wants to test if the average diastolic blood pressure in African-Americans is different than the average diastolic blood pressure in the general population. Note that the average diastolic blood pressure in the general population is 70 mmHG. The researcher retains the null hypothesis, so she therefore concludes... Group of answer choices The mean diastolic blood pressure in African-Americans is equal to that of the general population The mean diastolic blood pressure in African-Americans is different than that of the general population
Assume that adults have IQ scores that are normally distributed with a mean of 104.5 and a standard deviation 24.7. Find the first quartile Q,. which is the IQ score separating the bottom 25% from the top 75%. (Hint Draw a graph.) The first quartile is (Type an integer or decimal rounded to one decimal place as needed.)
