Newly purchased automobile tyres of a certain type are supposed to be filled to a pressure of 220 Nt/m. A recent random sample of 38 such Nt/m2 tyres from different cars operated by a large rental company yielded a sample standard deviation of 3.05 Nt/m and a sample mean of 221.04 Assuming the Central Limit Theorem applies and s σ, find the p-value associated with the following hypothesis test.
