Answer:
We reject H₀. We accept Hₐ (the cream can improve the the skin of more than 50%
Step-by-step explanation:
We have a proportion one tail test (right)
P₀ = 50 % = 0,5
P = 44/53 = 0.831
sample size = n = 53
Confidence interval = 0,95 α = 0.05 then z(c) = 1.64
1.-Hypothesis
H₀ null hypothesis P₀ = 0.5
Hₐ alternative hypothesis P₀ > 0.5
2.-Compute z(s)
z(s) = ( P - P₀ ) / √P₀Q₀/n ⇒ z(s) = (0.831 - 0.5 )/√0.5*0.5/53
z(s) = 0.3301/0.06
z(s) = 5.5
3.-Compare z(c) and z(s)
z(s) > z(c) 5.5 > 1.64
therefore z(s) is in the rejection region we reject H₀ . And accept Hₐ
The circumference of the circle that has a radius of 28 cm is: 175.9 cm..
<h3>What is the
Circumference of a Circle?</h3>
Circumference of a circle = 2 × π × r, where r = radius of the circle.
Given that a circle has:
radius (r) = 28 cm
Therefore:
Circumference of the circle = 2 × π × r
Plug in the value of r
Circumference = 2 × π × 28
= 175.9 cm.
