It is believed that the number of emergency room visits on Friday nights at hospitals follows a Poisson distribution with ì = 12. Suppose that 30 Friday nights are sampled and the number of emergency room visits (X) are recorded at a particular hospital. A) The hospital administration will conclude that the ER is seeing fewer patients than other hospitals if X < 11. Use the central limit theorem to approximate the probability that this conclusion is made when, in reality, the hospital is not different from the general population of hospitals. What type of error occurs if this conclusion is made? B) Actually, the number of ER visits on Friday nights does not follow a Poisson distribution but instead follows an unknown distribution with μ = 12 and ơ 5. Ūsing the central limit theorem, re-compute the probability found in (a).

see below

step-by-step explanation:

7.   there are 10 data points in the set.   the middle point is between 5 and 6.   the middle point in the top half is 8   and the middle point in the bottom half is 3. to find the iqr , take point 8 and subtract point 3

mid term   point 8 = 100   point 3 = 88

iqr = 100-88 = 12

final   point 8 = 93   point 3 = 78

iqr = 93 - 78 = 15

the final has the greatest iqr

6.   b - there is a high data value that causes the data set to be asymmetrical for the males: the data for males are high and asymmetrical .   there is an outlier for the males that skews the data

5.   the   iqr is a better measure of spread for the movies and basketball games.   since the basketball game has an outlier, we do not want to use standard deviation for measurement.  

3.   the exam median is much higher than the class median.   the median line is farther to the right on the exams

2.   there is no way to tell what the means are from the box and whisker plots.
