Answer:
B. 359
Step-by-step explanation:
Given that:
The margin of error (e) must be within 0.3 unit, The standard deviation (σ) = 2.9 and the the confidence level = 95% = 0.95
α = 1 =0.95 = 0.05
The z score of 0.025 corresponds to the z score of 0.0475 (0.5 - 0.025) which can be gotten from the normal probability table.
Therefore: 
The formula for the margin of error is given by:
Therefore the smallest sample size (n) is 359

Hello!
In order to find the cost of one pound of peanuts, we need to find 60% of two dollars. To do that, we convert 60% to a decimal, then multiply that to the cost of cashews, which is two dollars.
60 / 100 = 0.60
0.60 x $2.00 = $1.20
Therefore, the cost of one pound of peanuts is $1.20.
The cost of two pounds of peanuts can be found by multiply the cost of one pound of peanuts by two. Then, we add the cost of one pound of cashews, which is two dollars.
$1.20 · 2 = $2.40
$2.40 + $2.00 = $4.40
Therefore, the total cost of two pounds of peanuts and one pound of cashews is $4.40.
Question 1: $1.20
Question 2: $4.40
