Answer:2
Step-by-step explanation: two ones equal one two
Answer:
the lines are perpendicular
Answer:
not statistically significant at ∝ = 0.05
Step-by-step explanation:
Sample size( n ) = 61
Average for student leader graduates to finish degree ( x') = 4.97 years
std = 1.23
Average for student body = 4.56 years
<u>Determine if the difference between the student leaders and the entire student population is statistically significant at alpha</u>
H0( null hypothesis ) : u = 4.56
Ha : u ≠ 4.56
using test statistic
test statistic ; t = ( x' - u ) / std√ n
= ( 4.97 - 4.56 ) / 1.23 √ 61
= 2.60
let ∝ = 0.05 , critical value = -2.60 + 2.60
Hence we wont fail to accept H0
This shows that the difference between the student leaders and the entire student population is not statistically significant at ∝ = 0.05
1) you need divide 2 and 1 /4 by 1/4 to know the numbers of bowls of oatmeal before mags runs out the milk
x = 2+1/4/ 1/4 = 8+1/4÷1/4 = 9 AND THIS IS THE NUMBERS 0F OATMEAL THAH MAGS CAN HAVE WITH 2 1/4 OF MILK
1/3 (3y - 6) = 8
distribute: y - 2 = 8
add 2 to both sides: y = 10
10
