A newly installed automatic gate system was being tested to see if the number of failures in 1,000 entry attempts was the same as the number of failures in 1,000 exit attempts. A random sample of eight delivery trucks was selected for data collection. Do these sample results show that there is a significant difference between entry and exit gate failures? Use= 0.05.
| Truck 1 | Truck 2 | Truck 3 | Truck 4 | Truck 5 | Truck 6 | Truck 7 | Truck 8 | |
| Entry failures | 45 | 41 | 53 | 59 | 63 | 51 | 50 | 41 |
| Exit failures | 46 | 55 | 55 | 60 | 60 | 46 | 50 | 49 |
(a)Choose the appropriate hypotheses. Define the difference as Entry Exit. multiple choice 1
- H0:d= 0 versusH1:d 0
- H0:d 0 versusH1:d< 0
- H0:d 0 versusH1:d> 0
(b)Find the test statistictcalc.(Round your answer to 3 decimal places. A negative value should be indicated by a minus sign.) tcalc (c)Find the critical valuetcritfor= 0.05.(Round your answer to 3 decimal places. A negative value should be indicated by a minus sign.) tcrit (d)Find thep-value.(Round your answer to 4 decimal places.) p-value (e)State your conclusion. We (Click to select) fail to reject reject the null hypothesis.
