Atraining company provides classroom and online instruction to hundreds of people per month. as part of their training program a satisfaction survey is conducted at the end of each course. the training company believes there might be a change in its satisfaction rates. during the prior calendar year their satisfaction rate was 94.2%. over the past 6 months the number of satisfied responses was 824 out of 892 surveys. use the information provided to perform a 1 sample proportion test to determine if there is a difference between the current satisfaction rate and the prior year.

According to the sample data, we can claim that the current satisfaction rate is different from last year's.

Step-by-step explanation:

The explanation is in the picture.

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.  

the number of the people going.

step-by-step explanation:

the cost to buy one movie ticket is $7. if the total cost for the movie is a function of how many people go, then the input is : the number of the people going.
