Question

A random sample of pickles in a jar has the following weights in grams: 68, 54, 59, 70, 69, 65, 73, 59, 74, and 54

what is the nest prediction for the mean weight of all pickles in the jar?

64.5g

54g

66.5g

59g

Answer 1

68 + 54 + 59 + 70 + 69 + 65 + 73 + 59 + 74 + 54 = 586 grams
586 grams/10 = 58.6 grams (if you round it, you will get 59 grams)

hope this helps!!

Answer 2

64.5g

Explanation:

In order to solve this you just have to add all of the mass of the pickles and then you just have to divide by the number jars:

68+54+59+70+69+65+73+59+74+54=645 grams

So then you just divide this by 10:

645/10=64,5 grams as amean weight.

So the answer would be 64.5 grams as a mean weight.
