Answer:
The answer would be .03. How I solved the problem is I moved the decimal of .21 two places to the right resulting in 3. Then I moved the decimal back after getting the answer resulting in .03
Step-by-step explanation:
Option A is the correct answer
Answer: See explanation
Step-by-step explanation:
The null hypothesis H0: The null hypothesis states that there is no relationship between the two things that are being considered.
The alternative hypothesis is contradictory to H0 and it explains that there is a relationship between the two selected variables.
Based on the question, the null hypothesis H0 is that the rating of car is equal to 46.7 miles per gallon. μ = 46.7 MPG
The alternative hypothesis Ha is that the rating of the car is not equal to 46.7 Miles per gallon. μ ≠ 46.7 MPG
Answer:
Step-by-step explanation:
(a) R2 does not determine the level of correlation between two variables in statistics but rather it is used to determine the level of variance in a dependent variable that is explained by an independent variable. It is also known as coefficient of determination.
Pearson's correlation coefficient (r) will better explain a direct relationship between a country's literacy rate and life expectancy and the value obtained will better explain option a
(b) The slope of the line can predict an improvement in life expectancy but cannot guarantee this improvement. And as such, the use of the word "will" suggests a form of guarantee which is wrong in interpreting slopes.
Answer:
1 is 8
Step-by-step explanation: 2^3 is the same as 2x2x2. The exponent (3) is the number of times you multiply the number. 2x2 is 4. 4x2 is 8.
