I want to take a survey of students currently enrolled in my statistics course. There are 250 of them, so I number them from 001

emmasim [6.3K]

Answer:

174, 095, 148, 064, 239

Step-by-step explanation:

This is a "simple random sample" problem in which we randomly select a sample from a larger population therefore everyone has same probability of being selected.

Total students: 250

Labeled as 001, 002, 003,.....250

The generated random number table is:

69041 65817 87174 09514 8174 06423 93758 23612 17894

Now we have to arrange/sort this random number table in groups of three numbers.

690, 416, 581, 787, 174, 095, 148, 174, 064, 239, 375, 823, 612, 178, 94

Now we have to select first 5 distinct numbers in the range of 001 to 250

The first four numbers (690, 416, 581, 787) are out of range so ignore them.

Next we find our first three numbers (174, 095, 148)

Next we have number (174) again that we have already selected so ignore it.

Next we find our fourth and fifth number (064, 239)

We are done with selecting 5 numbers and these are:

174, 095, 148, 064, 239

Chaz is a 79.2 pound dog that was just adopted. Based on his foster home his daily energy intake is 1,840 kcal. Chaz’s new owner

zimovet [89]

Answer:

option (c)5 and $\frac{\textup{1}}{\textup{4}}$ cups

Step-by-step explanation:

Given:

Weight of Chaz = 79.2 pounds

Daily energy intake requirement = 1,840 kcal

Energy present in different brand food = 3,523 kcal/kg

Therefore,

the amount of food required = $\frac{\textup{Daily energy intake requirement}}{\textup{Energy present in different brand food}}$

the amount of food required = $\frac{\textup{1,840}}{\textup{3,523}}$

the amount of food required = 0.52228 kg

also,

1 kg = 1000 grams

therefore,

the amount of food required = 0.52228 × 1000 = 522.28 grams

now,

A cup of food weighs 100 grams

hence,

the number of cups required = $\frac{\textup{the amount of food required }}{\textup{Amount of food per cup}}$

the number of cups required = $\frac{\textup{522.28}}{\textup{100}}$

the number of cups required = 5.2228 ≈ 5 and $\frac{\textup{1}}{\textup{4}}$ cups

Hence, the correct answer is option (c)
