A large university is interested in the outcome of a course standardization process. They have taken a random sample of 100 stud
quester [9]

Answer:

Step-by-step explanation:

a)

Number of sample, n = 100

p = 0.78

q = 1 - p = 1 - 0.78

q = 0.22

For a confidence level of 90%, the corresponding z value is 1.645.

The formula for determining the error bound for the proportion is

z × √pq/n

= 1.645 ×√(0.78 × 0.22)/100

= 1.645 × 0.0414 = 0.068

The upper boundary of the population proportion is

0.78 + 0.068 = 0.85

The lower boundary of the population proportion is

0.78 - 0.068 = 0.71

b) For a confidence level of 95%, the corresponding z value is 1.96.

Therefore,

= 1.96 ×√(0.78 × 0.22)/100

= 1.96 × 0.0414 = 0.081

The upper boundary of the population proportion is

0.78 + 0.081 = 0.86

The lower boundary of the population proportion is

0.78 - 0.081 = 0.7

NeTakaya

Step-by-step explanation:

C(x)=4x^2-3\\\\C(0),\ C(-1),\ C(-2),\ C\left(-\dfrac{3}{2}\right)\\\\\text{Substitute each value}\ \left\{0, -1, -2, -\frac{3}{2}\right\}\ \text{instead}\ C(x):\\\\C(0)=4(0^2)-3=4(0)-3=0-3=-3\\\\C(-1)=4(-1)^2-3=4(1)-3=4-3=1\\\\C(-2)=4(-2)^2-3=4(4)-3=16-3=13\\\\C\left(-\dfrac{3}{2}\right)=4\left(-\dfrac{3}{2}\right)^2-3=4\left(\dfrac{9}{4}\right)-3=9-3=6
