In a regression analysis of a first-order model involving 3 predictor variables and 25 observations, the following estimated reg

ression equation was developed. Ŷ = 10 - 18x1 + 3x2 + 14x3 Also, the following standard errors and the sum of squares were obtained. sb1 = 3 sb2 = 6 sb3= 7 SST = 4800 SSE = 1296 At the 5% level, the coefficient of x2 a. is not found to be significant. b. is significant. c. cannot be tested, because not enough information is provided. d. should be estimated again, because it is incorrect in the above equation

Answer:

a. is not found to be significant.

Step-by-step explanation:

Regression analysis is a statistical technique which is used for forecasting. It determines the relationship between two variables. It determines the relationship of two or more dependent and independent variables. It is widely used in stats to find trend in the data. It helps to predict the values of dependent and independent variables. In the given question, there are 25 observations and the regression equation is given. X and Y are considered as dependent variables.

arleen has a gift card for a local lawn and garden store. she uses the gift card to rent a roller for 4 days. it cost $17 per da
kaheart [24]

Answer:

We use negative values for the money Arleen spends.

a) We determine the change to the value on her gift card:

4(-35)+(-9)= -140+(-9)=-149

b) We determine the amount on money she has left on the gift card after renting the tiller and buying the rake:

200+(-149)=51

Since she has got $51 on her gift card and a wheelbarrow is $50 she is able to buy it:

51>50

RESULT

a) -$149 less b) yes

zheka24 [161]

Answer with explanation:

⇒The Meaning of bisecting is two bifurcate , that is to divide into two parts, either you are bisecting a line or line segment.

⇒So, to bifurcate something that is segments and angles, you need either a line or line segment.

⇒So, the two steps which are same is , when bisecting segments and angles is,

 Option A→Draw a ray with one endpoint.

20 POINTS!!!
agasfer [191]

Answer:

<u>A. Probability of Russell = 12/37 or 32.4% (Rounding to the next tenth)</u>

<u>B. Probability of Peter = 5/74 or 6.8% (Rounding to the next tenth)</u>

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

               Guard Forward Center Totals

Over 6 feet 25     30        30        85

Under 6 feet 130 120      35        285

Totals           155 150      65        370

2. Russell is 5'9". What is the probability he is a forward?

Probability = Number of forwards under 6 feet/Total number of players

Probability = 120/370

Probability = 12/37 or 32.4% (Rounding to the next tenth)

3. Peter is 6'2". What is the probability he is a guard?

Probability = Number of guards over 6 feet/Total number of players

Probability = 25/370

Probability = 5/74 or 6.8% (Rounding to the next tenth)
