Answer:
10:40
Step-by-step explanation:
Answer:
The number cube as 12 sides, and if it is fair, then each one of the 12 numbers should have the same probability of being rolled.
This means that the probability of rolling a 2 should be equal to 1/12 = 0.0833
Remember that this is theoretical, we should expect to see this probability with a really high number of rolls.
On the first experiment, there were 10 rolls, and the number 2 showed up 4 times, then based on this, the relative frequency is equal to the quotient of the number of times that the 2 was rolled (4) and the total number of rolls
p = 4/10 = 0.4
This differs with the theoretical probability, we should expect that as we increment the number of rolls, the experimental probability should approximate to the theoretical one.
In the second experiment, we have 200 rolls, and the 2 was rolled 18 times. Then the experimental probability of rolling a 2 is:
p = 18/200 = 0.09
This is almost the same as the theoretical one.
Then we could conclude that the probability of rolling a 2 seems to be the one of fair dice.
Answer:
(a) Nominal data
(b) Calculating the mean is wrong
Step-by-step explanation:
Given
Basketball
Baseball
Football
Others
Solving (a): The level of measurement
In the given parameters, digit 1 to 4 are used to label each of the given sport.
When such labels are used, the type of data is nominal.
Solving (b): The error
In (a), we identified that the level of measurement is nominal. This implies that, the data are not counted, but instead they are categorized.
And as such, the mean of the data cannot be calculated.
B, C, and D is the answer
