Step-by-step explanation:
the mean is the average of the set of numbers, which makes it perfect for summarizing data.
Answer:
the probability that a random sample of 17 persons will exceed the weight limit of 3,417 pounds is 0.0166
Step-by-step explanation:
The summary of the given statistical data set are:
Sample Mean = 186
Standard deviation = 29
Maximum capacity 3,417 pounds or 17 persons.
sample size = 17
population mean =3417
The objective is to determine the probability that a random sample of 17 persons will exceed the weight limit of 3,417 pounds
In order to do that;
Let assume X to be the random variable that follows the normal distribution;
where;
Mean = 186 × 17 = 3162
Standard deviation =
Standard deviation = 119.57
Therefore; the probability that a random sample of 17 persons will exceed the weight limit of 3,417 pounds is 0.0166
Well a percent is always a number/100 (3%=3/100)
So what you have to do is put 66.6 over 100 and get
66.6/100 as your answer.
