Answer:
R = -0.8908
R² = 0.7935
Step-by-step explanation:
Given the data:
X :
5
3
6
3
4
4
6
8
Y :
13
15
7
12
13
11
9
5
Using technology, we could obtain the correlation Coefficient (R) using the Pearson correlation Coefficient calculator :
R = -0.8908 ; This means that there is a strong negative relationship between x and y. That is, an increase in x will lead to a corresponding decrease in y and vice versa.
The Coefficient of determination (R²) ; is obtained by taking the squared value of R
R² = (-0.8908)² = 0.7935 ; This means that about 79.35% of the variation is y is explained by the regression line.
Answer:
the correct option is p≥75
Step-by-step explanation:
the correct answer ir p≥75 because the sum of all other task she have done
$150+$65+$120+$100+$90=$525 so in order to reach $600(the amount she needs to pay her bills) u need to rest:
$600-the sum of the other 5 works ---> $600-$525=75 ----> this means that $75 is enough to pay her bills, but if she earns more than that it would be enough too.
ANWER= p≥75(higher or equal to 75)
Answer: 0.9987
Step-by-step explanation:
Given : The weights of newborn babies are distributed normally, with a mean of approximately 105 oz and a standard deviation of 10 oz.
i.e. 
and 
Let x represents the weights of newborn babies.
If a newborn baby is selected at random, then the probability that the baby weighs more than 75 oz will be :-
[using z-value table]
Hence, the required probability = 0.9987
