Answer:
The probability that on a given day below 6,214,323 drinks are sold is 0.8413.
Step-by-step explanation:
The provided information are:
Population mean = 6,205,195
Population standard deviation = 9,120.32
Consider, <em>X</em> be the random variable that represents the number of drinks that are sold on a given that is normally distributed with the mean = 6,205,195 and standard deviation = 9,120.32.
The probability that on a given day below 6,214,323 drinks are sold can be calculated as:
It must be noted that <em>P</em>(<em>Z</em> < 1.0008) = 0.8413 has been calculated using the standard normal table.
Hence, the required probability is 0.8413.
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.
