Open Tornadoes-HW6 data. Test if there is a significant difference between the number of tornadoes in August and the number of tornadoes in October on average. Answer questions 1 to 4.(Pick the closest answer) 1. What test did you perform? (6.25 points)

Use Two sided t-test

Step-by-step explanation:

Note that, there are other tools to test for significant difference such as simple regression or multiple regression but when comparing the results of two groups in terms of which is higher or lower, 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.

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.

yes   because as the functions are graphed they eventually will intersect unless otherwise
