In 1960, census results indicated that the age at which men in a certain region first married had a mean of 23.5 years. We want to find out if the mean age of first marriage has changed/differed from 23.5 years (µ≠23.5) since then. The 40 men in our sample first married at an average age of 24.3 years, with a sample standard deviation s of 5.3 years. The P-value is 0.346. State the conclusion using α = 0.10.
