In order to make statistical inferences when testing a population proportion p, which of the following conditions verify that inference procedures are appropriate? a. The data are collected using a random sample or random assignment.
b. The sample size is less than 10 percent of the population size.
c. np0≥10 and n(1−p0)≥10 for sample size n and hypothesized proportion p0.

a, b and c.

Step-by-step explanation:

The statistical inference may be defined as the process of using the data analysis to infer the properties of an underlying distribution for a probability.

In the context, for testing the population proportion p, the following conditions are used to verify the inference procedures so as to make the statistical inferences :

-- data that are collected by a random assignment or by a random sample.

-- sample size should be less than 10% of population size.

-- The and the for the sample size as well as for the  hypothesis proportion,

the answer is d. 75%
