Answer:
Each time your heart beats, an electrical signal travels through the heart. An EKG can show if your heart is beating at a normal rate and strength. It also helps show the size and position of your heart's chambers. An abnormal EKG can be a sign of heart disease or damage.

Answer:
(b) The interquartile range of B is greater than the interquartile range of A.
(d) The median of A is the same as the median of B.
Explanation:
Given
So:
Required
Select all true statements
(a) & (d) Median Comparisons
Arrange the data:
--- average of 5th and 6th
Option (d) is correct because both have a median of: 2
(b) & (c) Interquartile Range Comparisons
First, calculate the lower quartile (Q1)
[Odd n] [Even n]
This means that:
Next, calculate the upper quartile (Q3)
[Odd n] [Even n]
This means that:
The interquartile range is
So, we have:
(b) is true because B has a greater IQR than A
(e) This is false because some spread measures (which include quartiles and the interquartile range) changed when the 10th data is included.
The upper quartile and the interquartile range of A and B are not equal
This change in chromosome number is the result of B. Fertilization. Both of the individual gametes from the male and female combine together to produce a zygote or developing offspring that is diploid in most cases, and possess both sets of genetic content or chromosomal information, one from each parent.
