Answer:

4 minutes 3 seconds

Step-by-step explanation:

Step one:

Given data

A kangaroo hops 2 kilometers in 3 minutes

The rate/speed is

rate/speed= 2/3 km per minute

Required

the time taken to cover 3 km

Step two:

We know that

rate= distance/time

2/3= 3/t

cross multiply we have

2t=3*3

2t=9

divide both sides by 2

t= 9/2

t= 4.5 minutes

t= 4 minutes 3 seconds

Answer:

e)The information from the sample does not give enough information to support that more than 70% of Canadian children receive antibiotics during the first year of life

Step-by-step explanation:

The proportion we will use for the test is p = 70 %

From a random sample we got

n = 616

x = 438 then p₁ = 438/616 p₁ = 0,71 p₁ = 71 %

Then q₁ = 1 - p₁ q₁ = 1 - 0,71 q₁ = 0,29 q₁ = 29 %

a) Hypothesis test:

Null hypothesis H₀ p₁ = p

Alternative hypothesis Hₐ p₁ > p >70 %

CI = 95 % significance level α = 5 % α = 0,05

z(c) for α = 0,05 from z-table is z(c) = 1,64

b) To calculate z(s) = ( p₁ - p ) / √ p₁*q₁ / n

z(s) = ( 0,71 - 0,70 )/ √ 0,71*0,29/616

z(s) = 0,01 /0,01828

z(s) = 0,547 ≈ 0,55

c) p-value for z(s) is from z-table p-value ≈ 0,7088

d) p-value > 0,05 then we accept H₀ we don´t have enough evidence to reject H₀

e)The information from the sample does not give enough information to support that more than 70% of Canadian children receive antibiotics during the first year of life
