Chapter 11.1, Problem 27E

To determine

To calculate:

The histogram for the following data and tell that it is normal distribution or not:

Tickets sold	Frequency
$150-189$	$1$
$190-229$	$2$
$230-269$	$4$
$270-309$	$8$
$310-349$	$8$
$350-389$	$7$

Answer to Problem 27E

The histogram for the given data is:

  

The drawn histogram of given data is not a normal distribution.

Explanation of Solution

Given information:

Tickets sold	Frequency
$150-189$	$1$
$190-229$	$2$
$230-269$	$4$
$270-309$	$8$
$310-349$	$8$
$350-389$	$7$

Calculation:

Firstly need to draw a histogram of given data as and then check it for the normal distribution:

  

From the histogram diagram:

The shape of the curve is neither bell shaped nor symmetrical on both sides. In the normal distribution curve there is an equal distribution of data on each side of mean or median or data.

But in the drawn curve, there is no equal distribution on both sides of mean that’s why the histogram of given data is not a normal distribution.
