8 0

Answer:

500

Step-by-step explanation:

To determine whether the number rounds up or down, we look to the digit right of it. If it is 5 or bigger, we round up. In this case, we have exactly 5, so we round up to the nearest hundred, 500.

In contract negotiations between a local government agency and its workers,

Liono4ka [1.6K]

Answer:

a. 0.4

b. Not independent.

Step-by-step explanation:

a. We use the probability table attached below for our calculations.

-the probability that an agreement is reached on both sides is obtained from the table:

$P(Agreement)=\frac{400}{1000}\\\\\\=0.4$

b. To determine whether the two events are independent, we compare the probabilities $P(s)\times P(i)$ and $P(s \ and \ i)$ where i denotes insurance and s denotes salaries:

$P(s)\times P(i)=0.5\times 0.7\\\\=0.35\\\\\\P(s \ and \ i)=0.4$

Two events are considered to be independent, if and only if:

$P(A).P(B)=P(A\ and \ B)\\\\=>P(s).P(i)\neq P(s\ and\ i)$

Hence, the events are not independent.

A population has a mean muequals160 and a standard deviation sigmaequals20. Find the mean and standard deviation of the sampling

hoa [83]

Answer:

Mean 160

Standard deviation 2.63

Step-by-step explanation:

The Central Limit Theorem estabilishes that, for a random variable X, with mean $\mu$ and standard deviation $\sigma$ , the sample means with size n of at least 30 can be approximated to a normal distribution with mean $\mu$ and standard deviation $s = \frac{\sigma}{\sqrt{n}}$

In this problem, we have that:

$\mu = 160, \sigma = 20$

Find the mean and standard deviation of the sampling distribution of sample means with sample size n = 58.

Mean 160

Standard deviation $s = \frac{20}{\sqrt{58}} = 2.63$

How do i do these two while using a proportion?

AnnZ [28]

For #2, the proportion would be .40/.25 and x/15, then you would cross multiply to find x. and for #3 the proportion would be 15/6 and 75/x and again you would cross multiply to find x. (:
