Answer: 60 percent decrease
===========================================
Change in price = new - old = 100 - 250 = -150
The negative change means the price has gone down
Divide this change in price over the original 250 and convert to percent form
(change in price)/(original price) = -150/250 = -0.60
which converts to -60%
The negative percent change in price indicates a price decrease
So the price goes down by 60% meaning that it lost 60% of its value
Note how 60% of 250 is 0.60*250 = 150 which was the change in price computed earlier.
The random sample of the students is an illustration of sampling
The chi-square test for goodness of fit is inappropriate because the variable under study is not categorical.
<h3>How to determine the reason chi square is not appropriate?</h3>
The dataset is given as:
Monday 34
Tuesday 29
Wednesday 32
Thursday 28
Friday 19
The variable of the above dataset is a not a categorical dataset.
One of the conditions of the chi-square test for goodness of fit test is that the variable under study must be categorical.
Hence, the chi-square test for goodness of fit is inappropriate because the variable under study is not categorical.
