Answer:
Your answers may vary slightly. 5.2 Normal Distributions: Finding Probabilities If you are given that a random variable Xhas a normal distribution, nding probabilities corresponds to nding the area between the standard normal curve and the x-axis, using the table of z-scores. The mean (expected value) and standard deviation ˙should be given
Step-by-step explanation:
Answer:
my day is going good just got on the school
Your numbers are .17 and .165 meters
Let me explain each digit value:
Lets start with .17
Decimals are like whole numbers where each placement has a digit value
.1 is the tenths place
.07 is the hundredths place
Lets turn to .165
.1 is the tenths place
.06 is the hundredths place
.005 is the thousandths place
When seeing which decimal is larger, go along the tenths place and move along.
So as you can see
, .17 and .165 start with .1 so you can't see which is bigger by this. Now move on to the next digit. Which is larger? .17 or .16? As you should know, 7 is bigger than 6 so that means .17 is larger
Answer: .17 meters is larger than .165 meters
Answer:
6.7% of children who finished the race in under 45 seconds.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 75 seconds
Standard Deviation, σ = 20 seconds
We are given that the distribution of time of completion is a bell shaped distribution that is a normal distribution.
Formula:
P(finished the race in under 45 seconds.)
P(x < 45)
Calculation the value from standard normal z table, we have,
6.7% of children who finished the race in under 45 seconds.
