    The best estimate for the average temperature in October at 10 a. m. is 73.8 degrees Fahrenheit.

    Solution:

    Number of hours after 5 a. m.: x

    At 10 a. m.→x=10-5→x=5

    yˆ=-0.37 (5) ^2+6.15 (5) + 52.3

    yˆ=-0.37 (25) + 30.75+52.3

    yˆ=-9.25+30.75+52.3

    yˆ=73.8

    Answer: The best estimate for the average temperature in October at 10 a. m. is 73.8 degrees Fahrenheit.
