Answer:
There is no statistical evidence at 1% level to accept that the mean net contents exceeds 12 oz.
Step-by-step explanation:
Given that a random sample of ten containers is selected, and the net contents (oz) are as follows: 12.03, 12.01, 12.04, 12.02, 12.05, 11.98, 11.96, 12.02, 12.05, and 11.99.
We find mean = 11.015
Sample std deviation = 3.157
a)
(Right tailed test)
Mean difference /std error = test statistic
p value =0.174
Since p >0.01, our alpha, fail to reject H0
Conclusion:
There is no statistical evidence at 1% level to accept that the mean net contents exceeds 12 oz.
Answer:
Step-by-step explanation:
1. ⟾ one dozen = 12, so 2 dozen = 12×2=24
⟾ 24 Joe's doughnuts = $6
⟾ 1 Joe's doughnuts or unit / rate = $6/24 = $1/4.
⟾ so per doughnut unit rate is $ 1/4.
2. ⟾ 24 hours = 5432 miles.
⟾ 1 hours = 5432/24 hours
⟾ 1 hours = 226•333 miles.
⟾ so aryan drove in 226•333 miles in 1 hours.
