# OF ORDERS
MILES TRAVELED TO CUSTOMER
Prospective Advertisement
Deliveries within: 10 mile radius (required) 25 minute delivery time?
Including prep time and travel time Can we deliver on time more than ½ of the
time?
All qualifying orders over time guarantee: $10 gift certificate How many will we be giving out?
Is SnowPea able to achieve desired delivery time more
than half the time?
Desired Delivery Time: 10 mile radius Under 25 minutes (Total Time)
Null: SnowPea delivers on time MORE THAN half the time.
π > 0.5
Alternative: SnowPea doesn't deliver on time more than half the time.
π ≤ 0.5
test statistic (obs) 0.88 ZOBS
critical measure 1.64 ZCRIT
ZOBS > ZCRIT? Accept
p-value 0.37782
α-level 0.10
p-value < α-level? Acceptsample proportion=0.56population proportion= 0.5

Application
• Likelihood of not meeting requirements?•P-value= 38%
• Out of 100 orders?•($380.00)
Does Driver #3 really drive slower than the average?
Null: Driver #3 doesn’t drive slower than the average.µ≥ 24.3
Alternative: Driver #3 drives slower than the average. µ< 24.3
sample mean= 20.46population mean= 24.3std dev.= 5.8sample size= 17 # of tails= 16degrees of freedom=1
test stat. (obs) -2.73 TOBS
critical measure 1.34 TCRIT
TOBS > TCRIT? YES
p-value 0.01
α-level 0.10
p-value < α-level? YES
Does Driver #4 really drive slower than the average?
Null: Driver #4 doesn’t drive slower than the average.
µ≥ 24.3
Alternative: Driver #4 drives slower than the average.
µ< 24.3
test stat. (obs) -6.32 TOBS
critical measure 1.34 TCRIT
TOBS > TCRIT? yes
p-value 0.00
α-level 0.10
p-value < α-level? yes
sample mean= 17.66population mean= 24.3std dev.= 4.2sample size= 16# of tails= 15degrees of freedom=1
So what does this mean?
Driver #3 and #4 are below the company average speed.
Driver #3 and #4 need to pick up their speed or we recommend…
“YOU’RE FIRED”
CONCLUSION
1. DECIDE HOW IMPORTANT SPEED IS TO SNOWPEA AND TAKE APPROPRIATE ACTIONS.
2. IF GROSS REVENUE EXCEEDS THE AMOUNT LOST OUT OF 100 ORDERS WE WOULD RECOMMEND USING THE PROPOSED
ADVERTISEMENT IDEA.
