(1 poin) A random sampie of n - 45 is taken from a population of values to test the statistical hypotheses H0 : -25 HA :->25 The standard deviation in the population of values is-3 The mean and median of then- 45 data values in the sampie were found to be X -25,74 and X-2544 Find the value of the test statistic, using at least e decimals in your aswer. test statistic p) The P-value was found to be 00480622, cr 4.89622%. Select the prbabity expresson that was sed to fhd the P-value. D. P(T44> Toal E.AT> Teals 2

Explanation / Answer

= (25.74 - 25) / (3/sqrt(45))

= 1.655

B) p-value =P(Z > test statistic) = P(Z > 1.655) = 0.0489622
