Answer:
d. The survey result will be free from bias because a simple random sample was selected.
e. An SRS of 100 students is more likely than an SRS of 50 students to get a sample result close to the true population value.
Step-by-step explanation:
Simple Random Sampling is the sampling where samples are chosen randomly, where each and every unit has an equal chance of being selected in a sample.
a. <em>This option is false</em> because this sampling method is not affected by voluntary response bias.
b. Since the larger sample size gives the more accurate estimate. <em>Thus, this option is also false.</em>
c. No, this survey result will be not biased due to undercoverage. <em>Thus, this option is also false.</em>
d. Yes, since here each unit has equal and independent chance of being selected in the sample. Thus, this survey is free from bias and it is <em>correct option.</em>
e. Since the larger sample size gives the more accurate estimate.<em> Thus, this is also correct option.</em>
