Answer:
Step-by-step explanation:
Given that for a sample of eight bears, researchers measured the distances around the bears' chests and weighed the bears.
r = linear correlation coeff = 0.952
H_0: r =0\\
H_1 :r\neq 0
(Two tailed test)
r difference = 0.952
n=8
Std error = \sqrt{\frac{1-r^2}{n-2} } =0.12496
Test statistic t = 0.952/0.12496 = 7.618
Alpha = 0.05
df = 6
p value = 0.000267
This implies H0 is rejected.
There exists a linear relation between the variables and r cannot be 0
0.952^2 = 0.906=90.6% of variation in weight can be explained by the linear relationship between weight and chest size
this isn’t an answer but uhm, why are you doing 5th grade equations in HIGH SCHOOL
X = 4, y = 4
X = 2
y = 2
X × y =?
2 ×2 = 4
Answer: Derrick wants an air conditioner in his living room. It is a rectangular room that measures 13 feet by 15 feet. The room is well insulated and is on the east side of the house. It has an 8-foot-high ceiling. How large of an air conditioner would this room require? Round to the nearest thousand BTUs, hope this helped :)
Step-by-step explanation:
10^11 is 100,000,000,000
10^3 is 1000
1,10,100,1000,10000,100000,1000000,100000000,100000000000.
I think it might be 4 times bigger
