The precision scientific instrument company manufactures thermometers that are supposed to give readings of 0degreescat the freezing point of water. tests on a large sample of these thermometers reveal that at the freezing point of water, some give readings below 0degreesc(denoted by negative numbers) and some give readings above 0degreesc(denoted by positive numbers). assume that the mean reading is 0degreescand the standard deviation of the readings is 1.00degreesc. also assume that the frequency distribution of errors closely resembles the normal distribution. a thermometer is randomly selected and tested. a quality control analyst wants to examine thermometers that give readings in the bottom 4%. find the temperature reading that separates the bottom 4% from the others. round to two decimal places

(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.)
