A federal agency responsible for enforcing laws governing weights and measures routinely inspect packages to determine whether the weight of the content is at least as great as that advertised on the package. A random sample 18 containers whose packaging states that the contents weigh 8 ounces was Drawn. The contents were weighed and recorded. The sample mean was 7.96 ounces and the sample standard deviation is 0.085 ounces. Does the sample provide sufficient evidence to state that the true population mean weight his lesson 8 ounces? Find the P-value for this hypothesis test. Assume the population of weights is normally distributed.
Ha : y < 8 ounces
Round p-values tonfour decimals and include the leading zero.
