A sample mean, sample size, and population standard deviation are given. Use the one-mean z-test to perform the required hypothesis test at the given significance level. Use the P-value approach. x = 259, n= 15, o= 19, Ho = 250 , Ha: [ > 250 , a = 0.01 O A. z= 1.83; P-value = 0.0672; reject Ho O B. z= 1.83; P-value = 0.0672; do not reject Ho O C. z= 1.83; P-value = 0.0336, reject Ho O D. z= 1.83; P-value = 0.0336; do not reject Ho
