We suspect the overall mean monthly rent of apartments in Shadyside is higher than in Oakland, so we survey a random sample of Oakland apartments, and a random sample of Shadyside apartments.

A. matched pairs t-testB. two-sample t-testC. ANOVAD. chi-squared test for independenceE. inference for regression

B

Step-by-step explanation:

A. matched-pair t-test is used ot deterrmine whether two samples are different because sometihng has changed  and there are two distributions or there is effectively one distribution. In this scenario  only mean of two population is being compared and not the effect of any variable

B. two sample t-test  is used to determine whether average between two groups is significantly different or not. In this scenario, mean values of two populatinos are being compared.

C. ANOVAD is used to determine whether means of three or more statistically independent groups are significantly different or not. In this scenario, we have only two groups.

D. Chi-squaed test is used to test relationships between two variables. In this scenario, no relationship is being tested.

E. Inference of regression is used to determine how one population of x-values is dependent on another population of y-values based on the each individual sample values. In this scenario, we are not comparing individual values of two population

spinning a 1, 2, or 3. option d.

step-by-step explanation: when spinning a number graph up to 4, and aiming for any number less than 3, that automatically eliminates the number 4. now you have two numbers to spin on that are less than 3, but the number 3 is included in this question because it's no greater of an number than itself. i hope this you : )

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:
