Answer:
Normal distributions are symmetric around their mean. The mean, median, and mode of a normal distribution are equal. The area under the normal curve is equal to 1.0. Normal distributions are denser in the center and less dense in the tails.
Step-by-step explanation:
Extra Answered question:
How do you determine if a distribution is normal?
Answer: In order to be considered a normal distribution, a data set (when graphed) must follow a bell-shaped symmetrical curve centered around the mean. It must also adhere to the empirical rule that indicates the percentage of the data set that falls within (plus or minus) 1, 2 and 3 standard deviations of the mean.

Answer:
Step-by-step explanation:
1
- IQR's
- Ride A: 30 - 20 = 10
- Ride B: 30 - 10 = 20
- False, as 10 < 20
2
- Medians
- Ride A: 25
- Ride B: 20
- False, as 25 > 20
3
- Ranges
- Ride A: 45 - 5 = 40
- Ride B: 35 - 0 = 35
- TRUE, as 40 > 35
4
- Minimum
- Ride A: 5
- Ride B: 0
- TRUE, as 0 < 5
Answer:
Expected value would be $ 0.896
Step-by-step explanation:
Given,
The price of the lottery ticket = $44800000,
Also, the probability of winning the grand prize = .000000020,
Thus, the expected value of the lottery ticket = value of the lottery ticket × probability of getting the lottery ticket
= 44800000 × .000000020
= $0.896
Note : value of lottery ticket = prize amount - cost of each ticket,
Here the cost price of a ticket is not given,
That's why we did not consider it.
