Mrs. Pellegrin has weighed 5 packages of cheese and recorded the weights as \(10.2 \mathrm{oz}, 10.5 \mathrm{oz}, 9.3\) oz, \(9.8\) oz, and \(10.0\) oz. She calculated the standard deviation to be \(0.45\) oz.

The cheese factory lists the package weight at \(10 \mathrm{oz}\).

\(t=\frac{\bar{x}-\mu}{s / \sqrt{n}}\)

The t-statistic for a two-sided test would be
