Justin and hayley conducted a mission to a new planet, planet x, to study arm length. they took a random sample of 100 planet x residents. then they calculated a 95% confidence interval for the mean arm length. what does a 95% confidence interval for arm length tell us in this case? (i) i am 95% confident that this interval includes the sample mean (μ) arm length. (ii) i am confident that 95% of all planet x residents will have an arm length within this interval. (iii) i am confident that 95% planet x residents will have arm lengths within this interval. (iv) i am 95% confident that this interval includes the population mean arm length.

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.  

27 + 13x + 15 = (x + 5)( =

step-by-step explanation:

27 + 13x + 15 = (x + 5)( = 27 + 13x + 15 = (x + 5)( = 27 + 13x + 15 = (x + 5)( =

5/20 so 25%

step-by-step explanation:

answer: 8

step-by-step explanation: if you add the possibilities 5 different flavor and 3 different sizes 5+3=8
