Answer: Option (D) is the correct answer.
Step-by-step explanation:
A data that describes or tells what it is about or what is shows is known as descriptive statistic.
A descriptive statistic helps in summarizing a set of data which can be representation of the entire or sample of a population.
It basically provides a meaning to the information described by the data.
Thus, we can conclude that a statistic that describes a sampled group is called descriptive.
Answer:
99.7%
Step-by-step explanation:
Bell shaped curve by empirical rule is that if the standard deviation from the mean (left to right) is 1 deviation then about 68% of the data is in that range if it’s 2 standard deviations away then it’s 95% and 3 deviations away is 99.7%
142-100=42=3(14)
100-58=42=3(14)
Therefore the data is three standard deviations from the mean and this there is 99.7% of the data in this range.
The answer for that question is 12 m/s2. Your multiplying 25x12 which equals 300.
I think the answer is 273
You divide 31% by any of the other percentages (like for example, 25%) and then divide 93 by whatever you got as your answer (31 divided by 25 was 1.24, so I divided 93 by 1.24 to get 75) then repeat that with the other percentages and add them all up.
Answer:
11/45
Step-by-step explanation:
Total number of customers:
21+34+83+54+33=225
Number of customers that go 1 or 2 days:
21+34=55
55/225 simplifies to
11/45
when divided by 5
