An investigator has calculated the 99% confidence interval for a independent measures t test and found p open curly brackets minus 2.35 less or equal than italic mu subscript 1 minus italic mu subscript 2 less or equal than 5.05 close curly brackets equal 0.99 If the investigator wishes to test the null hypothesisH subscript 0 : italic mu subscript 1 minus italic mu subscript 2 equal 0 against the alternative H subscript 1 : italic mu subscript 1 minus italic mu subscript 2 not equal to 0 with italic alpha equal 0.01 , the investigator should: reject H subscript 0 fail to reject H subscript 0 reject H subscript 1 fail to reject H subscript 1

Solution

Calculated the 99% confidence interval (-2.35 , 5.05) contains 0 value.

The test is not significant.

The null hypothesis is not rejected at 0.01 level

The correct option is

fail to reject H₀
