The essential difference between Hypothesis Testing and Confidence Intervals is O a. Hypothesis Testing is guessing the value of u beyond the critical value using our sample mean and Confidence Intervals guess the range of values that is likely for u to assume O b. Hypothesis Testing is one of guessing which u our sample mean is likely to be estimating and Confidence Intervals guess the range of values that is likely for u to assume when Ho is true c. Hypothesis Testing is one of guessing which u our sample mean is likely to be estimating and Confidence Intervals guess the range of values that is likely for u to assume d. None of the above as Hypothesis Testing and Confidence Intervals are basically the same thing
