Find P(0), P(1), P(2), and P(3). Add together for the total probability. n = 10 x = 0,1,2,3 p = 0.45 Use a binomial probability table or a calculator. It will be easier than doing this by hand. If you must do this by hand, here is a formula: P(x) = (nCx)(p^x)[q^(n-x)] I'll...

Find P(8). n = 18 x = 8 p = 0.26 Use a binomial probability table or a calculator. If you must do this by hand, here is a formula: P(x) = (nCx)(p^x)[q^(n-x)] I'll let you take it from here.

Using an online calculator, I have the following: 12 data pairs (x,y): ( 12.0 , 24.0 ); ( 14.0 , 30.0 ); ( 15.0 , 36.0 ); ( 18.0 , 38.0 ); ( 20.0 , 65.0 ); ( 16.0 , 44.0 ); ( 14.0 , 36.0 ); ( 13.0 , 30.0 ); ( 18.0 , 39.0 ); ( 19.0 , 76.0 ); ( 20.0 , 80.0 ); ( 22.0 , 85.0 ); Re...

Here is your equation: yhat = 7.88 - 0.05x Substitute 55 for x and solve for yhat (that will be your predicted value). I'll show you how this is done: yhat = 7.88 - 0.05(55) = 7.88 - 2.75 = 5.13 yhat = 5.13 (cost per unit) I hope this helps.
statistics.urgent please help..
The sample mean is a point estimate of the population mean μ. You have two sample means, which are 7.23 and 6.49. Find the difference between the two means for your point estimate of µ1 - µ2.
