A population of values has a normal distribution with μ=41.6 and σ=42.6. You intend to draw a random sample of size n=146. Find P53, which is the score separating the bottom 53% scores from the top 47% scores. P53 (for single values) =  Find P53, which is the mean separating the bottom 53% means from the top 47% means. P53 (for sample means) =  Enter your answers as numbers accurate to 1 decimal place. Answers obtained using exact z-scores or z-scores rounded to 3 decimal places are accepted.

You are testing the claim that the mean GPA of night students is different from the mean GPA of day students. A sample of 27 night students and 26 day students and their GPA's are recorded below. Test the claim using a 5% level of significance. Assume the population variances are unequal and that GPAs are normally distributed. Give answers to 4 decimal places.
