Asample of 100 cans of peas showed an average weight of 14 ounces with a standard deviation of 0.7 ounces. if the distribution is fairly normal, how many cans will weigh over 14.7 ounces?

16

Step-by-step explanation:

We are given that A sample of 100 cans of peas showed an average weight of 14 ounces with a standard deviation of 0.7 ounces.

So,

Formula :

Since we are supposed how many cans will weigh over 14.7 ounces

So, x = 14.7

So, Using z table

P(z>1)=1-P(z<1)=1-0.8413=0.1587

Since A sample contains 100 cans

So, No. of cans will weigh over 14.7 ounces =

                                                                          =

So, no. of cans will weigh over 14.7 ounces is 16.

tube or goog would be a great resource to with that question
