The programs cost the same for 7 classes.
Given, no. of classes is represented by c, no. of dogs is represented by d, no. of hours is represented by h, the no. of programs is represented by p and the total cost is represented by t.
The first program charges $35 membership fee and $5 for each class.
The second program charges only $10 for each class.
Now the total cost say , for first program can be written in equation form as,
, here c is the no. of classes.
Similarly, the total cost say , for second program can be written in equation form as,
.
We have to find out the no. of classes for which the two programs cost the same.
according to the question,
Hence for 7 of classes the programs cost the same.

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>
<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 = 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>
