People end up tossing 12% of what they buy at the grocery store (Reader'sDigest, March 2009). Assume this is the true population proportion and thatyou plan to take a sample survey of 540 grocery shoppers to furtherinvestigate their behavior. Answer questions 8-10. The sampling distribution of p, the proportion of groceries thrown out byyour sample respondents isnot normal since n < 30.approximately normal if np 2 5 and n(1-P) > 5.approximately normal if np > 30 and n(1-P) > 30.approximately normal because p is always normally distributed.

Solution-: Given: n=540,p=0.12 (Or 12%) we choose correct option in the following (a) not normal…

Answered: The sampling distribution of p, the…

Mitchell is getting ready to take a baseball rules exam in order to becomne certified as a baseball umnpire in his local community. Past scores on the rules exam form a normal distribution with u = 80 and o = 6. Mitchell must score in the highest 25% of the distribution in order to become a certified umpire. Which minimum score does Mitchell need to obtain on the rules exam to become a certified umpire? OX= 76 O X- 84 OX= 86 OX-81
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

For the residents in 2014, use R to calculate the interval with 99% certainty that the interval contains the actual population mean of the residents by census tracts. Type in the interval with keyboard. We also know that in each year, the number of residents by census tract in the State of Maryland follows a normal distribution, and the variance in the number of residents within the State of Maryland is the same for different years.

K Determine whether the statement is true or false. If it is false, rewrite it as a true statement. A sampling distribution is normal only if the population is normal. Choose the correct answer below. OA. The statement is true. OB. The statement is false. A sampling distribution is normal if either n ≥ 30 or the population is normal. OC. The statement is false. A sampling distribution is normal only if n ≥ 30. O D. The statement is false. A sampling distribution is never normal. Z-S e
True or false- The interquartile range is the distance between the lowest score and in the middle 50% of the distribution, and the highest score in the middle 50% of the distribution.
The IQR represents the spread of the middle 50% of the data. Do you think the IQR in this problem is large or small? Here is the data. 0, 1, 1, 1, 2, 2, 2, 2, 2, 2, 2, 3, 3, 3, 3, 3, 3, 4, 4, 4, 4, 4, 5, 5, 6, 7, 13, 14 Median is 3. Min # is 0 Max # is 14 Q1 is 2 Q2 is 3 Q3 is 4 IQR=Q3 (4)-Q1(2) IQR=2

The sampling distribution of p, the proportion of groceries thrown out by your sample respondents is not normal since n < 30. approximately normal if np 2 5 and n(1-P) > 5. approximately normal if np > 30 and n(1-P) > 30. approximately normal because p is always normally distributed.
