Answer:
Step-by-step explanation:
Given that:
Number of lemon - lime flavored bottles = 8
Number of orange flavored bottles = 7
Bottles are picked one by one.
First for the friend and then for the person himself.
To find:
The probability that both the bottles drawn are of lemon-lime flavor.
Solution:
Total number of bottles available in the cooler = 8 + 7 = 15
Formula for probability of an event E can be observed as:
Now, lemon - lime flavored bottles left = 7
Total number of bottles left = 14
Required probability:
Answer:
a) The probability of obtaining a sample mean that is less than or equal to 1770 hours is P(M≤1770)=0.0013.
b) It is unusual, as there are only 13 chances in 10,000 (0.13%) of having this outcome.
Step-by-step explanation:
We have a population lifetime with mean of 1800 hours and standard deviation of 100 hours.
Samples of size n=100 are taken and tested.
We can calculate the probability of obtaining a sample mean that is less than or equal to 1770 hours using a z-score for the sample Mean M=1770 and then calculating its probability according to the standard normal distribution:
