Two types of chemical solutions, X and Y, were tested for their pH (degree of acidity of the solution). Analysis of 6 samples of X showed a mean pH of 6.72 with a standard deviation of 0.024. Analysis of 5 samples of Y showed a mean pH of 6.49 with a standard deviation of 0.032. Using a 0.05 significance level, determine whether the two types of solutions have different pH values.

pH measurements of a chemical solutions have mean 6.8 with
standard deviation 0.04. Assuming all pH measurements of this
solution follow a normal distribution, find the probability of
selecting a pH measurement at random that reads below 6.68 OR above
6.88 without using the
LSND program. (Write the answer in decimals)
