Correlation

Correlation defines a relationship between two independent variables. It tells the degree to which variables move in relation to each other. When two sets of data are related to each other, there is a correlation between them.

Linear Correlation

A correlation is used to determine the relationships between numerical and categorical variables. In other words, it is an indicator of how things are connected to one another. The correlation analysis is the study of how variables are related.

Regression Analysis

Regression analysis is a statistical method in which it estimates the relationship between a dependent variable and one or more independent variable. In simple terms dependent variable is called as outcome variable and independent variable is called as predictors. Regression analysis is one of the methods to find the trends in data. The independent variable used in Regression analysis is named Predictor variable. It offers data of an associated dependent variable regarding a particular outcome.

Question

NEED ANSWER FOR ALL

In 2016, the US poverty rate was 12.7%. During that year, 370 families where randomly selected in
Hawaii. Out of them, 30 were found to be living below the poverty line. At a level of significance of a
= 0.05, do the data provide sufficient evidence to conclude that, in 2016, the percentage of families
below the poverty line was lower in Hawaii than among all US families?
a. For this study, we should use Select an answer
b. The null and alternative hypotheses would be:
Ho:? v Select an answer v
(please enter a decimal)
Ha: ? v Select an answer v
(Please enter a decimal)
C. The test statistic ? v =
(please show your answer to 3 decimal places.)
d. The p-value =
(Please show your answer to 4 decimal places.)
e. The p-value is ? va
f. Based on this, we should Select an answer v the null hypothesis.
g. Thus, the final conclusion is that ...
O The data suggest the populaton proportion is significantly lower than 12.7% at a =
0.05, so there is sufficient evidence to conclude that the population proportion of
Hawaiian families who are below the poverty line is lower than the US as a whole.
O The data suggest the population proportion is not significantly lower than 12.7% at a =
0.05, so there is sufficient evidence to conclude that the population proportion of
Hawaiian families who are below the poverty line is lower than the US as a whole.
O The data suggest the population proportion is not significantly lower than 12.7% at a =
0.05, so there is not sufficient evidence to conclude that the population proportion of
Hawaiian families who are below the poverty line is lower than the US as a whole.

Arrange these steps in the correct order to prove that if you have an 8-gallon jug of water and two empty jugs with capacities of 5 gallons and 3 gallons, respectively, then you can measure 4 gallons by successively pouring some of or all of the water in a jug into another jug in the correct order. Rank the options below. Fill the 3-gallon jug from the 5-gallon jug, leaving (3, 2, 3). Empty the 5-gallon jug's contents into the 3-gallon jug, leaving (6, 0, 2), and then fill the 5-gallon jug from the 8-gallon jug, producing (1, 5, 2). Fill the 5-gallon jug from the 8-gallon jug, leaving the contents (3, 5, 0), where the ordered triple is used to record the amount of water in the 8-gallon jug, the 5-gallon jug, and the 3-gallon jug, respectively. Top off the 3-gallon jug from the 5-gallon jug, and there will be (1, 4, 3), with four gallons in the 5-gallon jug. Pour the contents of the 3-gallon jug back into the 8-gallon jug, leaving (6, 2, 0). ❤ ← ←
