Male crickets chirp by rubbing their front wings together. They chirp faster with increasing temperatures and slower with decreasing temperatures. The following table shows the number of chirps per second for a cricket, recorded at 10 different temperatures.

Chirps per second	29	23	28	26	26	23	21	25	22	23
Temperature	88	73	91	85	82	75	69	82	69	83

A- Find the least-squares line relating the number of chirps to the temperature. (Round your numeric values to three decimal places.)

y=?

B- If a cricket is monitored at a temperature of74degrees, what would you predict his number of chirps would be? (Round your answer to the nearest whole number.)-------? chirps
