Answer:
Result is statistically significant.
Step-by-step explanation:
Given that :
Chisquare statistic, χ² = 67.81
Critical value for the distribution, χ²critical = 3.84
α = 0.05
The Decison region :
If χ² statistic > Critical value ; Reject H0 ; this. Eans that result is statistically significant.
Therefore, since, 67.81 > 3.84 ; This means that the result is statistically significant at 0.05
Im debating between b. and c. but I'd go more with C.
D: 657.825
Start by converting 5 1/4 to a decimal. I’m assuming you have memorized 1/4 as a decimal, but if you haven’t yet, it’s 0.25. Add 0.25+5=5.25
One bag covers 125.3 ft square, but we have 5.25 bags. Change the one to 5.25 and multiply by 125.3.
Multiply 5.25x125.3
It equals 657.825

Answer:
42
Step-by-step explanation:
The equation is, c/7 = 6
c/7= 6
By multi[lying both sides with seven,
c = 6*7
c = 42
