The median is the halfway point,
Arrange the numbers in a line from smallest to largest:
01, 03, 14, 15 , 22, 35, 35, 43
There are 8 numbers.
When there is an even amount of numbers, find the middle two numbers, add them together and divide by 2.
15 + 22 = 37 /2 = 18.5
The median is 18.5
To find the median you line the numbers up in numerical order then you find the one in the middle.
If there are 2 numbers in the middle take the smaller and subtract it from the larger
Answer:
1. 0.35 miles per minute
2. 5.25 miles
Step-by-step explanation:
1. speed is 21 miles per hour
speed per minute = 21/60 = 0.35 miles per minute
2. distance covered in 15 minutes = 15*0.35
= 5.25miles
Can you please show a picture of your problem so i can better understand it
Answer and Step-by-step explanation:
a)
expected value for the difference in sample means=3.5-3.2=0.3
b)
standard deviation of the sampling distribution of the difference in sample means
=sqrt((0.5^2/40)+(0.8^2/40))
=0.1492
c)
z=(0.3-0)/0.1492
z=2.01
P(z>2.01)=0.0222
