,An Ogive is a cumulative True
percentage polygon
In a set of numerical data, the True
value of Q3 can never be
smaller than the value of Q1
The Poisson distribution can be False
used to model a continuous
random variable
The normal probability plot True
may be used to assess the
assumption of normality of for
a particular data set.
If the population distribution is True
unknown, in most cases the
sampling distribution of
sample mean can be
approximated by the normal
distribution if the sample
contains at least 3
observations
In forming a 90% confidence False
interval for a population
mean from a sample size of
22, the number of degrees of
freedom from a t- distribution
equals 22.
Suppose, in a testing True
hypothesis for the
population proportion, the p-
value is computed to be
0.043. The null hypothesis

conclusions about large
population based on small

The possible responses to True
