The median of the distribution is 4.

<h3>What is the median?</h3>

A histogram is used to represent data graphically. The histogram is made up of rectangles whose area is equal to the frequency of the data and whose width is equal to the class interval.

The median is the number at the center of the data set.

Arranging the numbers in the histogram in ascending order is: 2, 3, 3, 3, 3, 3, 4, 4, 4, 4, 4, 5, 5, 5, 5, 6, 6, 7, 8, 9, 10

Total numbers = 21
Median = 1/2 x (n + 1)

1/2 x 22 = 11th number 4

A physicist examines 23 sedimentary samples for mercury concentration. The mean mercury concentration for the sample data is 0.0

amm1812

Answer:

The 80% confidence interval is $0.0328 < \mu < 0.0392$

Step-by-step explanation:

From the question we are told that

The sample size is n = 23

The sample mean is $\= x = 0.036 \ cc/m^3$

The standard deviation is $\sigma = 0.012$

From the question we are told the confidence level is 80% , hence the level of significance is

$\alpha = (100 - 80 ) \%$

=> $\alpha = 0.20$

Generally from the normal distribution table the critical value of $\frac{\alpha }{2}$ is

$Z_{\frac{\alpha }{2} } = 1.282$

Generally the margin of error is mathematically represented as

$E = 1.282 * \frac{0.012 }{\sqrt{23} }$

=> $E = 0.00321$

Generally 80% confidence interval is mathematically represented as

$0.036 -0.00321 < \mu < 0.036 + 0.00321$

=> $0.0328 < \mu < 0.0392$
