Question

A sample of 100 scores has a mean of 62, a variance of 95, and an estimated standard error of 5. Which of these values is guaranteed to decrease if the sample size is increased to 110?

Answer #1

**A sample of 100 scores has a mean of 62, a variance of
95, and an estimated standard error of 5.**

**Now, the sample size is increased to 110.**

**We know, that the formula of standard error estimate is
given by**

**Where, sigma is the population variance and n is the
sample size.**

**So, the standard error is inversely proportional to the
sample size.**

**So, when the sample size is increased from 100 to 110,
then the standard error must decrease.**

**The answer is**

**The standard error is guaranteed to decrease, if the
sample size is increased to 110.**

Assume that population mean is to be estimated from the sample
size n =100, Sample mean x = 76.0cm, standard deviation s = 4.0cm.
Use the results to approximate the margin of error and 95%
confidence interval.

The distribution of sample means calculated using samples of
size 16 has a mean of 100 and a standard error of 2.25. What is the
variance of the original distribution?

Assume that a set of test scores is normally distributed with a
mean of 100 and a standard deviation of 10. Use the 68-95-99.7
rule to find the following quantities.
a. The percentage of scores less than 100 is __%
b. The percentage of scores greater than 110 is __%
c. The percentage of scores between 80 and 110 is __%
(Round to one decimal place as needed)

Question 11 options: that scores above the mean are distributed
the same as scores below the mean that extreme scores are possible
in a normal distribution that there are an infinite number of
possible normal distributions that this characteristic has no
practical implication
Question 12 (1 point) In a normal distribution with 3±1 (M±SD),
a researcher can appropriately conclude that about 84.13% of scores
were greater than 2. Question 12 options: True False

A normal population has mean 100 and variance 25. How large must
the random sample be if you want the standard error of the sample
average to be 1.5? (also calculate the probability of the average
exceeds 105 based on 16 observations from this normal
population)

Assume that a set of test scores is normally distributed with a
mean of 100 and a standard deviation of 10 . Use the 68-95-99.7
rule to find the following quantities. a. The percentage of scores
less than 110 is %. (Round to one decimal place as needed.) b.
The percentage of scores greater than 110 is nothing %. (Round to
one decimal place as needed.)

1.
a) Calculate the 95% margin of error in estimating a population
mean μ for the following values. (Round your answer to
three decimal places.)
n = 8,000, s2 =
64
b) Consider that for s2 = 64 and
sample sizes of 50, 100, and 500 the margins of error are 2.217,
1.568, and 0.701 respectively. Comment on how an increased sample
size affects the margin of error.
-As the sample size increases the margin of error also
increases.
-As...

Determine the minimum sample size required when you want to be
95% confident that the sample mean is within 1.2 unites of the
population mean. Assume that the population is normally distributed
with standard deviation σ = 4.8.
