Black_prince [1.1K]

Answer:

<em>The test statistic value Z = 4.64 > 1.96 at 0.05 level of significance</em>

<em>Null hypothesis is rejected </em>

<em>Alternative hypothesis is accepted</em>

<em>Test the claim that the proportion of all children in the town who suffer not from asthma is 11%</em>

Step-by-step explanation:

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

Given sample size 'n' = 167

Given data In a sample of 167 children selected randomly from one town, it is found that 37 of them suffer from asthma.

<em>Sample proportion </em>

$p^{-} = \frac{x}{n} = \frac{37}{167} = 0.2215$

<em>Given Population proportion 'P'</em> = 11% = 0.11

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

<em>Null Hypothesis : H₀ : p = 11</em>

<em>Alternative Hypothesis H₁: p≠11</em>

<u><em>Test statistic</em></u>

$Z = \frac{p^{-} -P }{\sqrt{\frac{P Q}{n} } }$

$Z = \frac{0.2215 -0.11 }{\sqrt{\frac{0.11 X 0.89}{167} } }$

Z = 4.64

<u><em>step(iii)</em></u>

<em> Critical value Z = 1.96 </em>

<em>The calculated value Z = 4.64 > 1.96 at 0.05 level of significance</em>

<em>Null hypothesis is rejected </em>

<em>Alternative hypothesis is accepted</em>

<u><em>Conclusion:-</em></u>

<em>Test the claim that the proportion of all children in the town who suffer not from asthma is 11%</em>

When dividing 82 by 43, Linda estimated the quotient to be 2. Examine Linda’s work, and explain what

Vanyuwa [196]

Answer:

82/43 = 1 and 39/43

Step-by-step explanation:

When dividing 82 by 43 , the operation follows;

82/43 = 1 and 39/43

This means the quotient is 1 and reminder is 39

However;

82/43 = 1.907 ------nearest whole number is 2.

so the quotient can be approximated to the nearest whole number as 2.

Dafna11 [192]

Acres of planted corn = (2/7) * (4/5)
