SAT

Ostrovityanka [42]3 years ago
7 0

Answer:

25 Minutes

Explanation:

Let time to setup small tent be denoted by S

Let time to setup Large tent be denoted by T

From the given information:

3S + 1T = 115   -- i

2S + 2T = 130 -- ii

Now these are two linear equations which can be solved

from (i)

T = 115-3S

add value of T in (ii)

2S + 2(115-3S) = 130

2S + 230 -6S = 130

Solving for S

4S = 100

S= 25

Which of the following conditions will create a biased estimator of a population parameter?.
UkoKoshka [18]

The option that represents the conditions that will create a biased estimator of a population parameter is;

D: The expected value of the estimator is not equal to the population parameter.

<h3>Biased and Unbiased Estimators</h3>

Usually in statistics research, there is what we call population parameters and sampling parameters.

The population parameters represent the full pool from which a sample can be taken while the sample parameters are gotten from the sample taken from the population.

Now, a statistic will be referred to as an unbiased estimator of a population parameter if the mean of the sampling distribution of the statistic is equal to the value of the population parameter.

In contrast to an unbiased estimator, a biased estimator of a population parameter is referred to as such if the mean of the sampling distribution of the statistic is not equal to the value of the population parameter.

The missing options are;

A. The sampling distribution of the estimator is skewed to the left.

B. The sampling distribution of the estimator is skewed to the right.

C. The sampling distribution of the estimator is not the same shape as the distribution of the population parameter.

D. The expected value of the estimator is not equal to the population parameter.

E. The variability of the sampling distribution of the estimator is not equal to the variability of the population parameter.

Describe the factors that affect energy use worldwide.
guajiro [1.7K]

Answer:

The more you use, the more you have

When you drink water (or any liquid).

Explanation:Similar for food: From a caloric standpoint, a McSupersized extra value meal should provide you with plenty of fuel to use.  But how do you feel after you eat one of those?  Unless you’re starving, less is more when it comes to food.Same for sleeping: Logging in 12-hour sessions seems like it should ready you for the day, but usually it leaves you dragging.  Unless you’re sleep deprived, it’s worth seeing what happens when you sleep just a little less.Healthy people drink a lot of water, as well they should.  But consider when you’re drinking that water: If you’re drinking it with your meal, you could be impairing your digestion.Not only does water dilute the gastric juices required to digest food, it also exits the stomach after just a few minutes, taking those juices with it and making digestion difficult.  And since digestion accounts for 5 to 15 percent of your energy expenditure, that’s something you should care about.
