The head of a computer science department is interested in estimating the proportion of students entering the department who wil

olya-2409 [2.1K]

Answer:

Step-by-step explanation:

From the given information:

At 95% Confidence interval level,Level of significance $\alpha$ 0.05, the value of Z from the standard normal tables = 1.96

Margin of Error = 0.10

Let assume that the estimated proportion = 0.5

therefore; the sample size n can be determined by using the formula: $n =(\dfrac{Z}{E})^2 \times p\times (1-p)$

$n =(\dfrac{1.96}{0.1})^2 \times 0.5\times (1-0.5)$

$n =(19.6)^2 \times 0.5\times (0.5)$

n = 96.04

n $\approx$ 96

Answer:

$x = 34.8^\circ$

Step-by-step explanation:

Given

See attachment for triangle

Required

Find x

To do this, we simply apply sin formula which is:

$sin(\theta) = \frac{Opposite}{Hypotenuse}$

In this case, it is:

$sin(x) = \frac{8}{14}$

$sin(x) =0.5714$

Take arcsin of both sides

$x = sin^{-1}(0.5714)$

$x = 34.84791$

$x = 34.8^\circ$ --- approximated
