Answer:
3 < x
Step-by-step explanation:
54 < 18x
Divide each side by 18
54/18 < 18x/18
3 < x
I would think it would be 0.22x-5=0.66. Al you have to do it take a calculator and do 2 divided by 3 for the first fraction. The second fraction would just be 2 divided by 3!

Answer:
The degrees of freedom are given by;
The significance level is 0.1 so then the critical value would be given by:
If the calculated value is higher than this value we can reject the null hypothesis that the arrivals are uniformly distributed over weekdays
Step-by-step explanation:
For this case we have the following observed values:
Mon 25 Tue 22 Wed 19 Thu 18 Fri 16 Total 100
For this case the expected values for each day are assumed:
The statsitic would be given by:
Where O represent the observed values and E the expected values
The degrees of freedom are given by;
The significance level is 0.1 so then the critical value would be given by:
If the calculated value is higher than this value we can reject the null hypothesis that the arrivals are uniformly distributed over weekdays
