Answer:
The appropriate probability model for X is a Binomial distribution,
X Bin (<em>n</em> = 5, <em>p</em> = 1/33).
Step-by-step explanation:
The random variable <em>X</em> can be defined as the number of American births resulting in a defect.
The proportion of American births that result in a birth defect is approximately <em>p</em> = 1/33.
A random sample of <em>n</em> = 5 American births are selected.
It is assumed that the births are independent, i.e. a birth can be defective or not is independent of the other births.
In this experiment the success is defined as a defective birth.
The random variable <em>X</em> satisfies all criteria of a Binomial distribution.
The criteria are:
- Number of observations is constant
- Independent trials
- Each trial has only two outcomes: Success and Failure
- Same probability of success for each trial
Thus, the appropriate probability model for X is a Binomial distribution, Bin (<em>n</em> = 5, <em>p</em> = 1/33).
Option d: Yes, Jacob is correct. The median amount he makes is $84.00 in a day.
Explanation:
It is given that Jacob's daily tips for week are $99, $78, $58, $91, $90, and $68.
We need to determine the median of how much money he makes in daily tips.
Thus, to determine the median, first let us arrange the tips in ascending order.
Ascending order: $58, $68, $78, $90, $91 and $99
Since, the group is an even number of terms, let us add the two middle terms and divide by 2.
Median =
Thus, the median is 84.
Hence, The median amount Jacob makes is $84.00 in a day.
Thus, Option d is the correct answer.
