Question

1. The CLT states: draw all possible samples of size
The result will be the sampling distribution of the means will
approach the as the sample size, n, increases. 2. The CLT tells us we can make probability statements about the
mean using the normal distribution even though we know
2.
Kit and Kat are in a loving relationship. They think Kat is pregnant and if she is they will remodel the spare bedroom into a baby bedroom and baby proof the house. Kit and Kat buy a pregnancy test. The null hypothesis is ____________________ 3.
True Ho is False |

Answer #1

The ________________ states that as samples size increases, the
shape of the distribution of all possible samples approaches
normality. The larger the sample, the less skew there tends to be,
and the more of a bell-shaped curve we tend to see.

3. In Hypothesis testing a Type 1 error is defined as:...

1. Are the following statements TRUE
or FALSE?:
(a) According to the Central Limit Theorem, given a large sample
size (N > 30), then a normal probability plot of the
same data would necessarily follow a straight line.
(b) A 95% confidence interval for a population mean that does
not include zero would also mean that a hypothesis test on the same
data would yield a significant result at the .05 level.
(c) The mean of a t-distribution with 5...

C. none of these
D. states that the mean of the sampling distribution of the
mean is equal to the population standard deviation divided by the
square root of the sample size

1.The Nearly Normal condition is met in one of either of two
ways: the sample size is large or...
a.the population (and sample) distribution are already normal
distribtuions.
b.we know the standard deviation of the population.
c.if the units we are measuring can only be positive (e.g.
weights of chickens).
d.the two samples are independent.

distributed. For the sampling distribution to be approximately
normal the central limit theorem requires the sample...
