Put the 3 on the y axis and go over three towards the x axis
The median of the data in the box plot is 6.
The first quartile is 5.5 (median of first half of data set)
The third quartile is 7 (median of upper half of data set)
The lower extreme is 3.5 (lowest number in the data set)
The upper extreme is 7.5 (highest number in the data set)
Add 2 to both sides: 3+2_> (<-the underline thing) , simplify 3+2 to 5: 5_>y, ur answer: y<_5
Hi there,
73 indeed a prime number
A prime number<span> (or a </span>prime) is a natural number<span> greater than 1 that has no positive divisors other than 1 and itself. A </span>natural number<span> greater than 1 that is not a </span>prime number<span> is called a composite </span><span>number!</span>
Answer: The margin of error = 3.71, confidence interval = (354.04, 361.46) and it means that mean cost is lies within the confidence interval.
Step-by-step explanation:
Since we have given that
Sample size = 400
Mean = $357.75
Standard deviation = $37.89
At 95% confidence level, z = 1.96
We first find the margin of error.
Margin of error is given by
95% confidence interval would be
Hence, the margin of error = 3.71, confidence interval = (354.04, 361.46) and it means that mean cost is lies within the confidence interval.
