I am having trouble solving this problem.  Can you please provide me with some help?  Thank you.  I appreciate it. Almonte. Inc., a maker of low-priced hair care products, claims that its hair spray lasts as long as the industry leader's higher-priced product.  You take a sample of 60 applications of Almonte's hair spray and 60 applications of the leading hair spray.  Results: On average, the Almonte applications held for 12.7 hours with a standard deviation of 1.4 hours.  On average, the leading hair spray lasted 11.8 hours with a standard deviation of 1.8 hours.  Set up a hypothesis test to test whether the difference in sample means is statistically significant.  Use a significance level of 1%.  Report and explain your conclusion.
