The melting point of 16 samples of a brand of olive oil was determined and the sample mean came out to be 95.52. Assume that the distribution of the melting point is normal with a standard deviation of 1.5. Test H0: μ=95 against Ha: μ̸ is not equal to 95 at the 10% significance level. Do the problem by first obtaining the rejection region and second, by using the p-value.

When 27.2 g of solid A, at its melting point of 34.0 °C, was added to 62.7 g of liquid A at 51.2 °C, the mixture cooled to 35.0 °C, with no solid remaining. Given the specific heat of liquid A (s = 0.798 J/g·°C), find the heat of fusion per gram of solid A. Assume that no heat enters or leaves the mixture. That is, assume that the mixture is an isolated system and therefore that q1 + q2...
