Question:

A supplier of imported vernier calipers claims that \(90 \%\) of their instruments have a precision of 0.999. Testing the null hypothesis \(p=0.90\) against the alternative hypothesis \(p eq 0.90\), what can we conclude at the level of significance \(\alpha=0.10\), if there were 665 calipers out of 700 with a precision of 0.999 ?
