The number that said it is morally wrong is 
The level of significance is 
The population proportion is 
Generally the sample proportion is mathematically represented as

=> 
=> 
The null hypothesis is 
The alternative hypothesis is 
The standard error is mathematically represented as

=> 
=> 
Generally the test statistics is mathematically represented as

=> 
=> 
Generally the p-value is mathematically represented as

From the the z-table

=> 
=> 
From the calculation 
Hence we fail to reject the null hypothesis
Thus there no sufficient evidence to conclude that 75% of adults say that it is morally wrong to not report all income on tax returns
Answer: Therefore, his son and daughter got Rs 200.
Step-by-step explanation:
6 kg of rice = 75*6 = Rs 450
2 packets of oil = RS 2*125 = RS 250
now total money he spent = Rs 450 + Rs 250 + Rs Rs 3,300
= Rs 700 + Rs 3,300
= Rs 4000
Money left = Rs 4,400-Rs 4000 = Rs 400
so
400/2 = Rs 200
