Answer: p-value is 0.016.
Step-by-step explanation:
Since we have given that
Sample mean = 19.4
Sample size n = 50
Standard deviation = 2
We need to find the test statistic value which is given by
p-value is given by
Hence, p-value is 0.016.
Answer:
-37m+6
Step-by-step explanation:
mkay so when working with simplifying any expressions like that, you wanna start with getting rid of your brackets. To do that, you simply take the number directly outside the bracket and you multiply it by everything inside. Let's take -9(m+2) first. You have to multiply everything inside the bracket by -9, so you have -9*m and -9*2, so you end up with -9m and -18. Now you do that to the second part of the equation (4*6 and 4*-7m) and you end up with 24 and -28m. Now you join all your terms together, and you have -9m-18+24-28m. Now all you do is add like terms (so -9m + -28m and -18+24) and you end up with a simplified expression of -37m+6. I hope this helped a little :)).
18/81 = 10/X
cross multiply
18*X =81*10
18x =810
divide both side by the coefficient of X which is 18
18x /18 = 810 /18
X= 45
Brenden. the more plants you test the easier it is to find the average instead of a smaller amount. hope this helped!
