The list of individuals from which a sample is actually selected is called the sampling frame. Ideally, the frame should list every individual in the population, but in practice, this is often difficult. A frame that leaves out part of the population is a common source of undercoverage. (a) Suppose that a sample of households in a community is selected at random from the telephone directory. Which households are omitted from this frame? households without telephones, those with only cell phones, and those with unlisted numbers households that do not answer the phone households that refuse to take part in surveys households with more than one telephone line What types of people do you think are likely to live in these households? These people will probably be underrepresented the sample. Select all that apply. those with extra time on their hands those who choose not to have landline phones those who can afford to have multiple phone lines those who do not wish to have their phone numbers published those who cannot afford a phone (b) It is usual in telephone surveys to use random digit dialing equipment that selects the last four digits of a telephone number at random after being given the exchange (the first three digits). Which of the households underrespresented in the sample will be included in the sampling frame by random digit dialing?

Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance
Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.
Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.

Could you help me to solve the part a second question ? Thank you
Transcribed Image Text:The list of individuals from which a sample is actually selected is called the sampling frame. Ideally, the frame should list
every individual in the population, but in practice, this is often difficult. A frame that leaves out part of the population is a
common source of undercoverage.
(a) Suppose that a sample of households in a community is selected at random from the telephone directory.
Which households are omitted from this frame?
households without telephones, those with only cell phones, and those with unlisted numbers
households that do not answer the phone
households that refuse to take part in surveys
households with more than one telephone line
What types of people do you think are likely to live in these households? These people will probably be underrepresented
the sample. Select all that apply.
those with extra time on their hands
those who choose not to have landline phones
those who can afford to have multiple phone lines
those who do not wish to have their phone numbers published
those who cannot afford a phone
(b) It is usual in telephone surveys to use random digit dialing equipment that selects the last four digits of a telephone
number at random after being given the exchange (the first three digits).
Which of the households underrespresented in the sample will be included in the sampling frame by random digit dialing?
