d
There no sufficient evidence to conclude that 75% of adults say that it is morally wrong to not report all income on tax returns
Step-by-step explanation:
From the question we are told that
The sample size is 
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
