Masja [62]

Answer:

Mean of the population having 6"-9" Hatching =38

Standard Deviation =4

Step-by-step explanation:

Confidence interval of 95% means that 95% of data lie within two standard deviations.

That is data values lie between 38-2×4 to 38 +2×4.

⇒Which is 38-8 to 38+8.

⇒30 to 46.

it is also given that margin of error is 2.5%.

So, the data value will lie between

Mean of beginning value to extreme value of 95% confidence level

  

So, Sample mean of this observation having 2.5% margin of error = 38

a boat costs $16600 and decreased in value by 14% per year. How much will the boat be worth after 11 years?
mr_godi [17]

The worth of boat after 11 years is $ 3159.3013

<em><u>Solution:</u></em>

Given that,

Boat costs $16600 and decreased in value by 14% per year

To find: Worth of boat after 11 years

<em><u>The formula for decreasing function is given as:</u></em>

y = a(1-r)^t

Where,

y is the value after "t" years

t is the number of years

a is the initial value

r is decreasing rate in decimal

<em><u>From given,</u></em>

a = 16600

t = 11

r = 14 \% = \frac{14}{100} = 0.14

<em><u>Substituting the values we get,</u></em>

y = 16600(1-0.14)^{11}\\\\y = 16600(0.86)^{11}\\\\y = 16600 \times 0.1903\\\\y = 3159.3013

Thus the worth of boat after 11 years is $ 3159.3013
