Ludmilka [50]

Answer:

The correct answer is: C. The value is a statistic because the 6076 adults in public restrooms are a sample.

Step-by-step explanation:

A sample statistic is a piece of statistical information you get from a part of a population. In this case, 6076 adults in public restrooms.

Now you have recognized the sample, and you infer some measure from this sample. In this case, 23% did not wash their hands before exiting.

Find the value of the lesser root of x2 - 6x + 8 = 0. A) -4 B) -2 C) 2 D) 4

tino4ka555 [31]

Answer:

The lesser root is 2..

Explanation:

x² - 6x + 8 = 0

x² -4x - 2x + 8 = 0

x(x - 4) -2(x - 4) = 0

(x - 2)(x- 4) = 0

x = 2 or 4

andrezito [222]

Answer:

0.7125

Step-by-step explanation:

The binomial distribution with parameters n and p is the discrete probability distribution of the number of successes (with probability p) in a sequence of n independent events.

The probability of getting exactly x successes in n independent Bernoulli trials = $n_{C_{x}}(p)^x(1-p)^{n-x}$

Total number of watches in the shipment = 50

Number of defective watches = 6

Number of selected watches = 10

Let X denotes the number of defective digital watches such that the random variable X follows a binomial distribution with parameters n and p.

So,

Probability of defective watches = $\frac{X}{n}=\frac{6}{50}=0.12$

Take n = 10 and p = 0.12

Probability that the shipment will be rejected = $P(X\geq 1)=1-P(X=0)$

$=1-n_{C_{x}}(p)^x(1-p)^{n-x}\\=1-10_{C_{0}}(0.12)^0(1-0.12)^{10-0}$

Use $n_{C_{x}}=\frac{n!}{x!(n-x)!}$

So,

Probability that the shipment will be rejected = $=1-\left ( \frac{10!}{0!(10-0)!} \right )(0.88)^{10}$

$=1-(0.88)^{10}\\=1-0.2785\\=0.7125$
