Delicious77 [7]

Answer:

<em>The interior length of the bassinet to ensure that 99 percent of newborn babies will fit   = 1.7 cm</em>

Step-by-step explanation:

<u><em>Explanation:</em></u>-

<em><u>step(i):</u></em>-

Given mean of population = 50 cm  

<em>standard deviation of Population = 5 cm</em>

<em>Given Margin of error = 10 cm</em>

<em>The Margin of error is determined by </em>

<em></em>M.E = \frac{Z_{\alpha } S.D}{\sqrt{n} }<em></em>

<u><em>Step(ii)</em></u><em>:-</em>

<em>Given level of significance ∝ = 99 % or 1 %</em>

Z₀.₀₁ = 2.576

10 = \frac{2.576 X 5}{\sqrt{n} }

\sqrt{n}  = \frac{2.576 X 5}{10}

√n = 1.3

squaring on both sides , we get

<em>n = 1.69≅ 1.7 cm</em>

<u><em> Final answer:</em></u>-

<em>The interior length of the bassinet to ensure that 99 percent of newborn babies will fit   = 1.7 cm</em>
