Answer:
Step-by-step explanation:
Sara sold $3350 in ads,
Kenny sold $1368, and
Leila sold $456
(a)
total sale=3350+1368+456=$5174
Sara's fraction=3350/5174=0.6475
Kenny's fraction=1368/5174=0.2644
Leila's fraction=456/5174=0.0881
(b)
total bonus=$150
Sara's bonus=150*0.6475=$97.12
Kenny's bonus=150*0.2644=$39.66
Leila's bonus=150*0.0881=$13.22

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
