Hey there!!
Let us take the price of the redwood as ' x ' and pine as ' y '
Then , we take it into an equation. We get,
50x + 80y = 285 -------------- ( 1 )
80x + 50y = 339 -------------- ( 2 )
Now, multiply the first equation with 8 and the second equation with 5
400x + 640y = 2280
400x + 250y = 1695
Now subtract the second equation from the first
390y = 585
y = 585 / 390
y = $1.5
Now substitute this into any equation
50x + ( 80 ) ( 1.5 ) = 285
50x + 120 = 285
50x = 165
x = 165 / 50
x = $3.3
Redwood = $3.3
Pine = $1.5
Hope helps!
X can be from -1.6 to -1.7 or x can be from -3.3 to 3.3
Answer:
He could increase the sample size
Step-by-step explanation:
In hypothesis testing, the error associated with the test is affected by a number of factors. The first factor is the level of significance, alpha. This is the probability of type 1 error. The probability of rejecting the null hypothesis when it is indeed true.
The second factor is the size of the sample used. The larger the sample, the smaller the error since the characteristics of the sample will be closer to those of the entire population on which inference is being made
The answer is 123684 x 10^1. Hope i helped.(whatever comes after ^ is an exponent)
