Brrunno [24]

The probability that the sample mean would be less than 43.4 dollars is 0.9292.

<h3>What is a probability?</h3>

Probability is the occurence of likely events. It is the area of mathematics that deals with numerical estimates of the likelihood that an event will occur or that a statement is true.

From the information, the mean cost of a five pound bag of shrimp is 42 dollars with a variance of 49 and a sample of 54 bags of shrimp is randomly selected.

Therefore, the probability will be:

P(x < 43.4)

Using normal distribution

= P(z < 43.4 - Mean( / 7/✓54)

= P(z < 43.4 - 42( / 7/✓54)

= P(z < 1.4697)

= 0.9292

The probability is 0.9292.

0.333333 = 1/3

can check through dividing 1 by 3

0.166666 = 1/6

0.1 = 1/10

0.66666 = 2/3

0.2 = 2/10 = 1/5

0.75 = 75/100 = 15/20 = 3/4
