   		True
   		False.

Answer 1

ANS 11) Yes, > 1.67 is sufficient to reject the null. because if t calculated is greater than 1.67 then we reject the null hypothesis.

ANS12) TRUE , In a dependent samples t-test, the sample sizes must be equal. in dependent sample t test there is only one sample that has been tested twice (repeated measures).

ANS 13) false ,The independent samples t-test is used when two separate sets of independent and identically distributed samples are obtained, one from each of the two populations being compared.the number of objects can be different
