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
<h3><u>Answer:</u></h3>
- The class will need 8 yards.
- 1 student = 3/6 rope
- => 16 students = 3/6 x 16
- => 48/6 = 16 students
- => 8 yards = 16 students.
Therefore, the class will need 8 yards.
Hoped this helped.
