You successfully completed statistics, and the Math Department Chair recruited you to be a tutor. It’s day one on the job, and y

our first pupil is correcting her mistakes on a recent statistics exam. She incorrectly listed the reasons that researchers use random sampling when conducting a survey. She wants to know why researchers should use a random sample to conduct a survey. Check all that apply. Group of answer choices A random sample is likely to avoid bias. In a random sample some members of the population are more likely to be selected than others. Random samples provide consistency and systematically favor one choice over every other choice in each survey question. Random sampling will provide a more representative sample of population. Researchers can use a random sample to draw conclusions about the population.

Answer:

Step-by-step explanation:

Ok, so we have to help your pupil (lets call her Jane) figure out "why researchers should use a random sample to conduct a survey". So, i will list all of the choices.

  • A random sample is likely to avoid bias
  • In a random sample some members of the population are more likely to be selected than others
  • Random samples provide consistency and systematically favor one choice over every other choice in each survey question
  • Random sampling will provide a more representative sample of population
  • Researchers can use a random sample to draw conclusions about the population

Random sampling is used to get the best average, and not favor any one opinion. For example, if you were trying to figure out the daily spending budget of people, you wouldn't just go to the upper clas part with all the rich people, you would survey from all over the town to get results from all kinds of people. So, the answers are:

  • A random sample is likely to avoid bias (because thats exactly what they do)
  • Random sampling will provide a more representative sample of population (because they are designed to do that)
  • Researchers can use a random sample to draw conclusions about the population (thats why they take the samples)

Hope this helps

Please help I need the 3 equations to solve for each type of point. ​
Law Incorporation [45]

Answer:

f = 0

x > 2y

x ≤ 8

S ≥ 18

Step-by-step explanation:

Let 'f' represent the number of free throws.

Let 'x' represent the number of 2 - point baskets.

Let 'y' represent the number of 3 - point baskets.

Let S represent the Season high.

1) Ryan says he did not shoot any free throws.

⇒ f = 0

2) 2 - point baskets more than twice the number of 3 - point baskets.

⇒ x > 2y

3) Number of two points is less than or equal to 8.

⇒ x ≤ 8.

4) Last Season high, he had scored 18 points. Note that the problem says, Ryan equaled or bettered than last season high. That means he should got at least 18 points this season. So, the equation would be:

S ≥ 18

A scale measures weight to the nearest 0.5 lb. which measurement shows an appropriate level of precision for the scale? A. 140lb
Yuri [45]

Answer:

The correct answer is option C.

Step-by-step explanation:

Precision is defined as the closeness of two or more measurements to each other.This is how much close are the series of measurements of a same object to each other.

For example : If we measure volume of water in flask which comes out to be 2 mL and again on measuring for the number of times we get same value of 2 mL. Hence, this measurement will said to be precise.

A scale measures weight to the nearest 0.5 lb.So, from the given options the measurement which is appropriate to the given precision scale is 140.5 lbs.

I’m just not getting it! I need step by step.
Alexus [3.1K]

Answer:

7x + 10 + x + 20 + 2x \\ 7x + x + 2x + 10 + 20 \\ 10 x + 30 \\ x =  \frac{30 }{10}  \\ x = 3 \\ (7x + 10) = 7 \times 3 + 10 = 31 \\ (x + 20) = 3 + 20 = 23 \\ (2 \times 3) = 6

pogonyaev

9514 1404 393

Answer:

  -31/15

Step-by-step explanation:

Put the numbers in the expression and do the arithmetic.

  c-4x=-\dfrac{7}{15}-4\cdot\dfrac{2}{5}=-\left(\dfrac{7}{15}+\dfrac{8}{5}\right)\\\\=-\left(\dfrac{7}{15}+\dfrac{24}{15}\right)=\boxed{-\dfrac{31}{15}}
