Answer:
<u>Use Two sided t-test</u>
<u>Step-by-step explanation:</u>
Note that, there are other tools to test for significant difference such as simple regression or multiple regression<em> but when comparing the results of two groups in terms of which is higher or lower</em>, then a two sided t-test would be best appropriate.
Since we want to know if there is a significant difference between the number of tornadoes in August and the number of tornadoes in October on average we use the two sided t-test because a Two sided t-test can show the possibility of positive or negative differences.
If you look up “Four 4s Challenge” on yt you should find a couple videos explaining it! i just watched a little bit of one so i’ll try and help now though.
I’ll do 1-5 for you and try my best to explain :)) and if you need more answers or more help just let me know
So first, we need to find out how to get 1 using four 4s
1. (4/4)/(4/4)
this would read “four divided by four divided by four divided by four” which equals 1
2. 4/4+4/4
3. (4+4+4)/4
4. 4*(4-4)+4
5. (4*4+4)/4
Remember that you’ve gotta use an equation with just four 4s to get to every number
