Answer:

a.Reject the null hypothesis

Explanation:

Null Hypothesis is rejected & not rejected as per following rules :

  • Rejected, when calculated value of t statistic >  the tabulated value of t statistic at the significance level.
  • Not rejected, when calculated value of t statistic < the tabulated value of t statistic at the significance level.

At significance level 0.05 two tailed test, implies 0.025 at each tail of the distribution. This corresponds to t statistic tabulated value = 1.96

The calculated value of t statistic = 2.095 [Given]

As t statistic's calculated value 2.095 > t statistic's tabulated value 1.96 The Null Hypothesis is rejected
