Answer 1

Answer #1

Option C is the correct answer here.

Option C is +/- 2.101

Here in the two tailed independent t test here the values of t and alpha is given and when we insert the values in the formula answer will come out in this.

Formulae is

The given things in question is-t(df=15)= 0.1

After putting the value of this while Calculating it.

T= X1- X2/SE

here t= 0.2 and just calculate it for X1 and X2 the value of SE comes to be n1 -1 and N2- 2 sqare root of(S sqare/Na - S sqare/ Nb)/ Ma - Mb

The value comes to be -

+/- 2.101

Thanks
