The data set represents the income levels of the members of a country club. Estimate the probability that a randomly selected member earns at least $98,000.
112,000 126,000 90,000 133,000 94,000 112,000 98,000 82,000 147,000 182,000 86,000 105,000
140,000 94,000 126,000 119,000 98,000 154,000 78,000 119,000
MY ANSWER IS 0.6. AM I RIGHT?
To estimate the probability that a randomly selected member earns at least $98,000, you need to consider the total number of members who earn at least $98,000 compared to the total number of members in the country club.
To find the probability, you need to calculate the number of members who earn at least $98,000 and divide it by the total number of members in the country club.
In this case, we have the following data set representing the income levels of the country club members:
112,000 126,000 90,000 133,000 94,000 112,000 98,000 82,000 147,000 182,000 86,000 105,000 140,000 94,000 126,000 119,000 98,000 154,000 78,000 119,000.
To find the number of members who earn at least $98,000, we can go through the data set and count the values that are greater or equal to $98,000. In this case, the values are:
112,000 126,000 133,000 112,000 98,000 147,000 182,000 105,000 140,000 126,000 119,000 98,000 154,000 119,000.
Counting these values, we find that there are 14 members who earn at least $98,000.
To calculate the probability, you need to divide the number of members who earn at least $98,000 (14) by the total number of members in the data set (20). Therefore, the probability is:
14/20 = 0.7.
So the correct answer is 0.7, not 0.6.
