The cost of a daily newspaper varies from city to city. however, the variation among prices remains steady with a standard devia
Tanya [424]

First, we establish our hypothesis:

<span>Null hypothesis H0: μ = $1.00  </span>

Alternative hypothesis Ha: μ ≠ $1.00

<span>Let’s say X  = the sample average cost of a daily newspaper = 0.96</span>

u = population mean cost = 1.00

S = sample standard deviation = 0.18

Calculating for z value:

z = (X – u) / S

z = (0.96 – 1) / 0.18

z = – 0.222

From the standard distribution table at this z value, p-value = 0.4129

Since alpha = 0.01, the decision therefore is:

<span>Do not reject the null hypothesis because the p-value is greater than 0.01. There is enough evidence to support the claim that the mean cost of newspapers is $1. </span>

How do you find the area of a triangle?
Firlakuza [10]

with it's formula

Area of Triangle = (1/2)(ab)sin(C) – This formula is used when two sides and the angle in between them are known. It can be obtained from the basic formula, Area of Triangle = 0.5 × base × height. The height with respect to side 'a' can be written in as b×sin(C), where C is the angle between a and b.
