Two students analyzed the same data from a study. student 1 used a one-sided test and student 2 used a two-sided test. the p-value of the test corresponding to student 1's analysis was found to be 0.042. what is the p-value for the test performed by student 2?

Step-by-step explanation:

Given that one of two students analysed the data by using one sided test and got p value as 0.042

Second student analysed the same data by using two tailed test and got p value

We have to find the second p value

p value one tailed = 1/2 ( p value of two tailed value)

Hence

the p-value for the test performed by Student 2=2(0.042) = 0.084

intensity of the vector is v= √37 ≈ 6.08 units and make angle ∡α ≈ 9.46° with east direction

step-by-step explanation:

required vector is consists of the two componentsvx= 2+4=6 units   and vy= 1 unit and vx ⊥ vywe will use pythagorian theorem to find intensity of the vector vv∧2 = vx∧2 + vy∧2 => v = √vx∧2 + vy∧2 = √6∧2 + 1∧2 = √36+1 = √37 ≈ 6.08 unitsthe angle ∡α between vector and east direction we wil find with tanαtanα = 1/6 => α = arc tanα = arc 1/6 => α ≈ 9.46°

hope this

10.416 meters per second

step-by-step explanation:

distance=1 00 meters

time= 9.6 seconds in decimal form or 9 3/5 as a mixed number

average speed= 100/9.6

=10.416 meters per second or 10 52/125 as a mixed number.
