Answer:
There is a linear correlation between chest size and weight,0.8482
Step-by-step explanation:
Given that for a sample of eight bears, researchers measured the distances around the bears' chests and weighed the bears.
the value of the linear correlation coefficient is r = 0.921.
i.e. there is a strong positive correlation from the value of r.
(Two tailed test at 5% level for correlation coefficient)
Test statistic t =
p value <0.00001
Since p is less than 0.05 we reject H0
a) There is a linear correlation between chest size andweight
b)-- R^2 = 0.8482 proportion of the variation in weight can be explainedby the linear relationship between weight and chest size
Answer: The approximate surface area of the larger pyramid is 159.31 ft².
Step-by-step explanation:
A pyramid is a solid,
And, When two solids are similar then the ratio of their surface area is the square of the scale factor of similarity.
Here, the scale factor of similarity
Thus, by the above property,
It is given that, the smaller pyramid has a surface area of 25.49 ft²,
