Wouldn't it be 140 bags with one of each in it; unless you need to use all the candies?
1 plus 3 equals 4
Your answer is 4
Answer:
See explanation below.
Step-by-step explanation:
We are looking for the mean and the standard deviation of the sampling distribution of the sample of mean x, given that the mean and standard deviation of sampled population are as follows:
Mean=μ= 77.4
Standard deviation = σ = 4.0
Sample size n = 255
so, the mean of sample mean x will be same as mean of the sampled population:
μₓ = μ = 77.4
and the standard deviation of sample mean x will be standard deviation of the sampled population divided by square root of sample size:
σₓ = σ / √ n
= 4.0 / √225
= 4.0 / 15
= 0.3
