Given:
value of the test statistic is t20 = 1.95
corresponding p-value of 0.0653 at the 5% significance level

No, I can't conclude that the correlation coefficient differs from zero because the p-value, which is 0.0653 exceeds 0.05. 

The correlation coefficient differs from zero when the p-value is less than 0.05.

Answer:

y = -0.8x - 5

Step-by-step explanation:

x1 = (XA + XB) / 2 = -5

y1 = (YA + YB) / 2 = -1

m = (XA - XB) / (YA - YB) = -0

__________________________________________

(y - -1) = -0.8(x - -5)

y - -1 = -0.8x - 4

y = -0.8x - 4 + -1

y = -0.8x - 5

Due tomarrow please help!!!!!!!!!!!!!!!!!!!!!!!!! Identify the independent and dependent variables in the following statement. T
miskamm [114]
The independent variable is the rate that water is flowing into the pool, and the dependent variable is the depth of water in the pool.

I believe this would be the case due to the fact that we are not in control of the flow yet the flow impacts the depth. So flow would be independent while the pool depth would be dependent on the rate of flow.

.For a hockey game, tickets are $220 for
Romashka [77]

Answer:

900 front row seats

Step-by-step explanation:

Tickets for front row seat = 220 dollars (y)

Cost of remaining seats ticket = 50 dollars (z)

Number of front row seats = x

Number of remaining seats = 2050 (w)

Total amount earned when stadium is full = 300,500 dollars (T)

so if we formulate this using our variables y,z,x,w and T problem it becomes:

y*x + z*w = T, which says the

Tickets for front row seat times Number of front row seats plus Cost of remaining seats ticket times Number of remaining seats gives us Total amount earned by the stadium.

220*x + 2050*50 = 300500

220*x = 300500-102500

220*x = 198000

divide both side by 220

x = 900
