Use normal distributions to approximate binomial distributions

Full solution

Q. Below is the problem statement for an exercise asking you to go through a hypothesis test. Which calculator function are you going to use to find the test statistic or p-value?

\newline

You wish to test the following claim

\left(\mathrm{H}_{\mathrm{a}}\right)

at a significance level of

\alpha=0.05

\newline

\begin{array}{l} \mathrm{H}_{\mathrm{o}}: p=0.42 \\ \mathrm{H}_{\mathrm{a}}: p>0.42 \end{array}

\newline

You obtain a sample of size

n=143

in which there are

73

successful observations. For this test, you should NOT use the continuity correction, and you should use the normal distribution as an approximation for the binomial distribution.

Claim and Sample Information: We have a claim that the population proportion $p$ is greater than $0.42$ , and we want to test this claim using a sample of size $n=143$ with $73$ successes.
Calculator Function Selection: Since we're testing a single proportion without continuity correction and using normal approximation, the appropriate calculator function is ＂ $1$ -PropZtest＂.
Input for Calculator: We input the following into the calculator: $p_0$ (hypothesized proportion) = $0.42$ , $x$ (number of successes) = $73$ , $n$ (sample size) = $143$ , and we select the alternative hypothesis ＂ $p > 0.42$ ＂.
