Answer:
The order of fruit from least to greatest weight is -
Apple , pear, navel orange, grapefruit
Step-by-step explanation:
P.S - The exact question is -
Given - Sophia buys an apple that weighs 0.45 pound, a grapefruit that weighs pound, a navel orange that weighs
pound, and a pear that weighs 0.5 pound.
To find - What is the order of the fruit from least weight to the greatest weight ?
Proof -
Weight of apple = 0.45 pound
Weight of grapefruit = pound = 0.75 pound
Weight of navel orange = pound = 0.625 pound
Weight of a pear = 0.5 pound
As,
0.45 < 0.5 < 0.625 < 0.75
So, The order of fruit from least to greatest weight is -
Apple , pear, navel orange, grapefruit
Answer:
a)
b) From the central limit theorem we know that the distribution for the sample mean is given by:
c)
Step-by-step explanation:
Let X the random variable the represent the scores for the test analyzed. We know that:
And we select a sample size of 64.
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".
Part a
For this case the mean and standard error for the sample mean would be given by:
Part b
From the central limit theorem we know that the distribution for the sample mean is given by:
Part c
For this case we want this probability:
And we can use the z score defined as:
And using this we got:
And using a calculator, excel or the normal standard table we have that:
