The proportion in a t-distribution less than -1.4 is 0.095 and this can be determined by using the given data.

Given :

Assume the samples are random samples from distributions that are reasonably normally distributed, and that a t-statistic will be used for inference about the difference in sample means.The samples have sizes $\rm n_1$ = 12 and $\rm n_2$ = 12.T statistics = -1.4

The degree of freedom is given by:

$\rm df=Min.(n_1-1,n_2-1)$

$\rm df=Min.(12-1,12-1)$

df = Min.(11 , 11)

df = 11

Now, compute the proportion in t-distribution:

$\rm P(t_{df}$

$\rm = P(t_{11}1.4)$

= 0.095

The proportion in a t-distribution less than -1.4 is 0.095 and this can be determined by using the given data.

Use a t-distribution to answer this question. Assume the samples are random samples from distributio

Answer from: alailatrenee18541

The degrees of freedom is 11.

The proportion in a t-distribution less than -1.4 is 0.095.

Step-by-step explanation:

The complete question is:

Use a t-distribution to answer this question. Assume the samples are random samples from distributions that are reasonably normally distributed, and that a t-statistic will be used for inference about the difference in sample means. State the degrees of freedom used. Find the proportion in a t-distribution less than -1.4 if the samples have sizes 1 = 12 and n 2 = 12 . Enter the exact answer for the degrees of freedom and round your answer for the area to three decimal places. degrees of freedom = Enter your answer; degrees of freedom proportion = Enter your answer; proportion

Solution:

The information provided is:

$n_{1}=n_{2}=12\\t-stat=-1.4$

Compute the degrees of freedom as follows:

$\text{df}=\text{Min}.(n_{1}-1,\ n_{2}-1)$

$=\text{Min}.(12-1,\ 12-1)\\\\=\text{Min}.(11,\ 11)\\\\=11$

Thus, the degrees of freedom is 11.

Compute the proportion in a t-distribution less than -1.4 as follows:

$P(t_{df}$

$=P(t_{11}1.4)\\\\=0.095$

*Use a t-table.

Thus, the proportion in a t-distribution less than -1.4 is 0.095.

Answer from: Quest

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
