The number of newly reported crime cases in a county in New York State is shown in the accompanying table, where x represents the
number of years since 2008, and y represents number of new cases.
Write the linear regression equation that represents this set of data,
rounding all coefficients to the nearest hundredth. Using this
equation, find the projected number of new cases for 2016, rounded to
the nearest whole number.

(b) suppose that consolidated power decides to use a level of significance of α = .05, and suppose a random sample of 100 temperature readings is obtained. if the sample mean of the 100 temperature readings is x⎯⎯ = 60.990, test h0 versus ha and determine whether the power plant should be shut down and the cooling system repaired. perform the hypothesis test by using a critical value and a p-value. assume σ = 5. (round your z to 2 decimal places and p-value to 4 decimal places.)
