Answer:
approximately Normal, mean 8.1, standard deviation 0.063.
Step-by-step explanation:
Previous concepts
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The central limit theorem states that "if we have a population with mean μ and standard deviation σ and take sufficiently large random samples from the population with replacement, then the distribution of the sample means will be approximately normally distributed. This will hold true regardless of whether the source population is normal or skewed, provided the sample size is sufficiently large".
Let X the random variable weights of 8-ounce wedges of cheddar cheese produced at a dairy. We know from the problem that the distribution for the random variable X is given by:
We take a sample of n=10 . That represent the sample size.
What can we say about the shape of the distribution of the sample mean?
From the central limit theorem we know that the distribution for the sample mean is also normal and is given by:
approximately Normal, mean 8.1, standard deviation 0.063.
Answer:
The correct answer is:
44% (B.)
Step-by-step explanation:
number of times flipped = 50 times
number of times red landed face-up = 22 times
∴ frequency of chip landing with red side face up = (number of times red landed face-up) ÷ (number of times flipped) × 100
= (22 ÷ 50) × 100 = 44%
$1.08
you would multiply your cost (1.00) by 8% which is equivalent to .08 and then add to to the original cost. or to skip the middle step just multiply it by 1.08 since you are adding the 8% to 100% of the original cost
