A 90% confidence interval for u using the sample results X = 131.2, s=55 , and n= 50 Round your answer for the point estimate to
Ilya [14]

Answer:

131.2 ;

12.8 ;

(118.4, 144)

Step-by-step explanation:

Given :

X = 131.2, s=55 , and n= 50

Point estimate of the mean :

Since, sample size is large (n > 30) ; the sample mean = population mean according to the center limit theorem :

Margin of Error = Zcritical * s / sqrt(n)

Zcritical at 90% = 1.645

Margin of Error : 1.645 * (55 / sqrt(50))

Margin of Error : 1.645 * 7.7781745

Margin of Error = 12.795097

Margin of Error = 12.8

The confidence interval (C.I) :

C.I = x ± margin of error

C. I = 131.2 ± 12.8

(131.2 - 12.8) ; (131.2 + 12.8)

(118.4, 144)

A rectangular box has length 9 inches, width 7 inches, and a height of 15 inches. find the angle between the diagonal of the box
uysha [10]
0.92085175 radians  
Let's first calculate the length of the diagonal of the base. Using the Pythagorean theorem:
 b = sqrt(9^2 + 7^2) = sqrt(81 + 49) = sqrt(130) = 11.40175425 
 Now the length of the diagonal to the box. Once again, using the Pythagorean theorem:
 d = sqrt(15^2 + 11.40175425^2) = sqrt(225 + 130) = sqrt(335) = 18.84144368 
 We now have a right triangle where we know the lengths of all three sides. The lengths are:
 a = 15
 b = sqrt(130) ≠11.40175425
 c = sqrt(335) ≠18.84144368
 
 we want the angle opposite to side a. So
 tan(A) = 15/11.40175425 = 1.315587029
 A = atan(1.315587029)
 A = 0.92085175 radians
