Answer:

the population after 52 days is $34,804.27

Step-by-step explanation:

Given that

There is a population of the rabbits i.e. 192

And, the growth rate is 10%

We need to find out the population after 52 days

So,

= 192 × e^(0.10 × 52)

= $34,804.27

The quality control manager of a light bulb factory needs to estimate the average life of a large shipment of light bulbs. The p

eimsori [14]

Answer:

b) yes

The manufacturer has the right to state that the light bulbs last on average 400 hours

Step-by-step explanation:

Explanation:-

Given sample size 'n' = 64

Given standard deviation of the Population (σ)=100

Mean of the sample (x⁻) = 350 hours

95% of confidence interval is determined by

$(x^{-} -Z_{0.95} \frac{S.D}{\sqrt{n} } , x^{-} +Z_{0.95} \frac{S.D}{\sqrt{n} } )$

( $(350 -1.96 \frac{100}{\sqrt{64} } , 350+1.96\frac{100}{\sqrt{64} } )$

(350-24.5 , 350+24.5)

(325.5 , 374.5)

Conclusion:-

Yes

The manufacturer has the right to state that the light bulbs last on average 400 hours
