Answer: The answer is (c) estimate of a variable, as determined through a sample.

Step-by-step explanation: We are given four different options out of which one gives the perfect definition of a parameter.

In mathematics, a parameter is defined as a constant or a variable in a function that determines a particular form of the function but not its general form. For example, f(x) = k x, where 'k' determines only the gradient of the line described by f(x).

In statistics, a parameter is defined as a variable that enters in the mathematical form of a distribution such that the possible values of the variable correspond to different distributions.

Thus, the correct option is (c) estimate of a variable, as determined through a sample.

Determine operating cost per mile. Choose the right answer.

SVETLANKA909090 [29]

Answer: $0.1428/mi or about 14 cents per mile

Steps:

While the cost of car = $5,000.00 is not an operating cost, the annual decrease of value is. So, given that the market value after 1 year = $3,800, the value loss is 5000-3800=$1200 for the year.

Add cost of gas and oil = $750.00, Repairs/Maintenance = $250.00, Insurance = $300.00, to get $2500 total operating cost.

The cost per mile is $2500/17500 miles = $0.1428/mi or about 14 cents per mile

Ket [755]

Answer:

The mean is 40.35 and the standard deviation is 0.13.

Step-by-step explanation:

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean $\mu$ and standard deviation $\sigma$ , the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean $\mu$ and standard deviation $s = \frac{\sigma}{\sqrt{n}}$ .

For a certain type of olivine assembly, the silicon dioxide (SiO2) content (in weight percent) in a randomly chosen rock has mean 40.35 and standard deviation 0.4.

Sample of 10:

By the Central Limit Theorem, the mean is 40.35, and the standard deviation is $s = \frac{\sigma}{\sqrt{n}} = \frac{0.4}{\sqrt{10}} = 0.13$

The mean is 40.35 and the standard deviation is 0.13.
