Part (i)

1) AB is perpendicular to BC, ED is perpendicular to CD, BC = CD (given)

2) Angles ABC and CDE are right angles (perpendicular lines form right angles)

3) Angles ABC and CDE are equal (all right angles are equal)

4) Angles ACB and DCE are equal (vertical angles are equal)

5) Triangles ABC and EDC are congruent (ASA)

Part (ii)

6) AB = DE (corresponding parts of congruent triangles are equal)

Lemons tastes sour to some people. This sourness is inherited through the TAS2R38 gene. About 65% of the population has this gen

Minchanka [31]

Answer:

We are given:

$\hat{p}=0.65$

Margin of error $E=0.02$

Confidence level = 0.99

We need to find the sample size to estimate the proportion of people who carry the TAS2R388 gene.

The formula for finding the sample size is:

$n=\hat{p} (1-\hat{p})\left (\frac{z_{\frac{0.01}{2}}}{E} \right )^{2}$

Where:

$z_{\frac{0.01}{2}}=2.576$ is the critical value at 0.01 significance level.

Therefore, the required sample size is:

$n=0.65(1-0.65) \left(\frac{2.576}{0.02} \right)^{2}$

$=0.2275 \times 16589.44$

$=3774.1 \approx 3774$

Therefore, the required sample size is 3774
