Express the angle in radian measure. 60°

Strike441 [17]

Pi radians =180 degrees:

That is, π rad = 180°

60° in radian measure = 60° × π / 180°

60° × π / 180° = 1/3 π rad
= 0.33333333333π rad
= 1.0471975512 rad

Dmitry [639]

Answer:

The test statistic

Z = 1.149

Since the calculated value of Z = 1.149 is less than 1.96 at 5% (0.05) level of significance.

The null hypothesis is accepted

Hence the proportion is not equal 0.04

Step-by-step explanation:

Given data a random sample of 300 circuits is tested, revealing 16 defectives.

The proportion of success

$p = \frac{16}{300} =0.053$

Null hypothesis:- H₀ = P ≠0.04

Alternative hypothesis:- H₁ = P =0.04

Q = 1-P = 1-0.04=0.96

Level of significance ∝ =0.05

The test statistic

$Z= \frac{p-P}{\sqrt{\frac{PQ}{n} } }$

now substitute all values, we get

$Z= \frac{0.053-0.04}{\sqrt{\frac{0.0384}{300} } }$

on calculation, Z = 1.149

Since the calculated value of Z = 1.149 is less than 1.96 at 5% (0.05) level of significance.

The null hypothesis is accepted .

Hence the proportion is not equal 0.04
