We are to find the probability that the weight of total luggage for a sample of 100 passengers is less than 2100.
The mean weight of the luggage of passengers will be 2100/100 = 21.
So we have to find the probability of the mean weight to be less than 21.
Average weight = u = 19.4
Standard deviation = 5.3
Since we are dealing with a sample of 100. We will use the standard error.
Standard error =

Now we have to convert the weight to z-score

From z table we can find the probability of z being less than 3.018 is 99.87%.
Therefore, the probability that for (a random sample of) 100 passengers, the total luggage weight is less than 2,100 lbs is 99.87%
Answer:
E
Step-by-step explanation:
1+2+2+1
A geometric sequence deals with multiplying...u have to multiply by a common number to get the next number
1/4 * 2 = 1/2
1/2 * 2 = 1
1 * 2 = 2
2 * 2 = 4
so ur geometric sequence is : 1/4, 1/2, 1, 2, 4...with a common ratio of 2
