When a truckload of apples arrives at a packing plant, a random sample of 150 is selected and examined for bruises, discoloratio
myrzilka [38]

Answer:

c. 0.088

Step-by-step explanation:

Let p(s) be the proportion of apples defected in the sample. The probability that p(s)<0.05 can be calculated by calculating z statistic of 0.05:

\frac{p(s)-p}{\sqrt{\frac{p*(1-p)}{N} } } where

  • p(s) = 0.05
  • p is the proportion of the apples in fact defected (0.08)
  • N is the sample size (150)   Then,

z(0.05)=\frac{0.05-0.08}{\sqrt{\frac{0.08*0.92)}{150} } }=-1.354

And P(z<-1.354)≈0.0879

Therefore the probability that  a random sample of 150 among 8% defected apples can be accepted is 0.088.

75% OFF!
ICE Princess25 [194]
$676.

If the sale price of the coat is $169, you are looking for the original price. I like to think about it in the sense that if an item is 75% off, you are paying 25% of the original amount. Using that logic, in order to determine the sale price you would use the equation

Original price * 25% = $169

To solve for the original price:

Original price = $169/.25 = $676.
