Answer:
Total number of trees planted = 
trees
Step-by-step explanation:
Trees planted by each student = 
Total number of students = 
Using unitary method to find total number of trees planted by all the students in school.
1 student plants = trees
student would plant = 
We apply the product rule of exponents to multiply ![[a^xa^y=a^{x+y}]](https://tex.z-dn.net/?f=%5Ba%5Exa%5Ey%3Da%5E%7Bx%2By%7D%5D)
⇒ 
⇒ 
⇒ trees
Total number of trees planted = trees

Answer:
e. reject the null hypothesis the p value is less than 0.05. therefore the difference is significant.
Step-by-step explanation:
given that after comparing response times between the audio and picture portions of the MIT test, the t-test resulted in a t-value of 2.97.
test statistic t = 2.97
Sample size n =250
Critical value of t at 95% is 1.96
We find that test statistic absolute value is greater than 1.96
So p value would be less than 0.05
This implies that null hypothesis stands in the rejected region.
So reject null hypothesis would be correct conclusion. Sample size cannot be said to be small as more than 30 itself is a good sample size.
e. reject the null hypothesis the p value is less than 0.05. therefore the difference is significant.
Answer:
.8
Step-by-step explanation:
5 red marbles, 2 Green marbles and 3 black marbles = 10 marbles
P (red or black) = number of red or black/ total
= (5+3)/10
=8/10
decimal form = .8
