In 1997, a survey of 960 households showed that 172 of them use email. Use those sample results to test the claim that more than 15% of households use email. use a 0.05 significance level, and use this information to answer the following question.
what is the test statistic?
what is the P-value?
This would be most appreciated on how to do this, cause i have been pulling my hair out on how to get the anwser for this.
Thank you.
