Researchers want to examine whether or not there is a difference in birthweight for mothers who smoke and mothers who do not smoke. Their alternate hypothesis is Ha: μ1 ≠ μ2.They collect smoking status and birthweight information for 189 pregnancies. For your convenience, I have prepared an Excel file with the data titled: data_final_smoking_bw. xlsx. Preview the document Use a t-test to test the hypothesis that there is a difference in birthweight for mothers who smoke and mothers who do not smoke at the α = 0.05 level. Assume unequal variance between the groups. What is the p-value for this result?

(8+64)^2= 5184 < answer

step-by-step explanation:

2^3 = 8

4^3= 64

(8+64)^2 = 5184

1. she sold more on day 2 because if you turn .85 into a fraction{85/100} and you give 7/9 and 85/100 the same denominator{180} you can see which one has the bigger numerator and that one will be the most sold.

2. yes it is in simplest form, because if you look at 38 and 53 's greatest common factor, you cant find one so you cant reduce it

3. no, this is not a prime factorization because the numbers are not all prime numbers, the correct prime factorization is:   2 x 5 x 2

4.   in 12 days he will run and play trumpet again

work 4 4: 123123123123

                123412341234     in 12 days he will play the trumpet and run on the same day

step-by-step explanation:

i am normally pretty good at math, im new to this site, but im 1 grade ahead in my math, i luv math try my answers out, see how they work

answer: 2/13 chance i think ( ͡° ͜ʖ ͡°)( ͡° ͜ʖ ͡°)
