the standard normal distribution is a normal distribution
whose - ANSWER-
mean is µ=0 and standard deviation
o(sigma)=1
a z-score tells us - ANSWER-how many standard deviations we
are away from
the
mean
every normal distribution - ANSWER-is symmetric about its
mean µ, with a
standard deviation of o
(sigma)
According to the Chi-squared table if your df+5 and your
alpha level =0.05, at what value will you reject the null
hypothesis a- >11.07 b- <11.07 c- >9.49 d- <9.49
, e- <0.05 - ANSWER-a- >11.07
which of the following graphic techniques can be best used to
summarize qualitative data?
a-bar graph b-
box plot
c-dot plot
d-stem-and-leaf plot - ANSWER-a-bar graph
which of the following is a necessary condition for the Central
Limit Theorem to
be used? - ANSWER-the sample size must be large (ex.
at least 40)
Which of the following is false about the Central Limit Theorem?
- ANSWER-it is
only value only if the population
distribution is normal
Investigators feel it is important to reduce the probability of
Type 1 error so they set alpha at 0.01. The resulting p-value
from their study is 0.02. a- the study result might be a Type II
error b-the study result is statistically significant c-the study
result is not important to patient care
d-the study's power is 99% e-under the assumption that the null
hypothesis is true, the probability of getting a result as large or
larger that 0.01 is 2% - ANSWER-a- the study result might be a
Type II error
