A restaurant decides to test their oven's thermostat to see if it is working properly, that is, if the real temperature inside the oven is the same as the temperature to which the thermostat was set. Twenty times, the oven was set at 350 degrees and then temperature was measured with thermometer.
Ho: mu = 350 and Ha: mu is not equal to 350
The test statistic is equal to 2.30.
Determine the p-value?
A. p-value is between 0.20 and 0.10
B. p-value is between 0.10 and 0.05
C. p-value is between 0.05 and 0.02
D. p-value is between 0.025 and 0.010
