Major league baseball has had 11 different single-season home run records since 1876. The records are 5, 9, 14, 27, 29, 54, 59,
stira [4]

All plots correctly show the range, 5–73.

The 1st, 2nd, and 4th choices correctly show the median, 54.

Of those, the 2nd and 4th choices correctly show the first quartile, 14.

Of those, only the 2nd choice correctly shows the third quartile, 61.

_____

There are an odd number of data points, so the middle one is the median. That value divides the remaining points in to two groups of 5. That number is also odd, so its median is the middle of that group. If we use x for the lower half and y for the upper half, you have

... (5 x 14 x x) 54 (y y 61 y 73)

Suppose taxi fare from Logan Airport to downtown Boston is known to be normally distributed with a standard deviation of $2.50.
Mariulka [41]

Answer:

95% Confidence interval for taxi fare:  ($20.5,$24.2)

Step-by-step explanation:

We are given the following data set: for fares:

$22.10, $23.25, $21.35, $24.50, $21.90, $20.75, and $22.65

Formula:

Mean = \displaystyle\frac{\text{Sum of all observations}}{\text{Total number of observation}}

Mean =\displaystyle\frac{156.5}{7} = 22.35

95% Confidence interval:

\bar{x} \pm z_{critical}\frac{\sigma}{\sqrt{n}}

Putting the values, we get,

z_{critical}\text{ at}~\alpha_{0.05} = 1.96

22.35 \pm 1.96(\frac{2.5}{\sqrt{7}} ) = 22.35 \pm 1.85 = (20.5,24.2)
