vagabundo [1.1K]

Answer:

The correct option is d) convenience sample

Step-by-step explanation:

In statistics, we use different sampling techniques to gather a chunk of sample data from a very large population.

There are many sampling techniques and out of them one is convenience sampling.

Convenience Sampling:

The convenience sampling is defined as the sample data which is readily and conveniently available.

Examples:

1. Asking people questions at a place that is convenient for you.

2. Asking your friends or family members

3. A college student asking for student's opinion at the college who is surveying for his thesis.

In the given scenario, Kristen Ashford has list of 5,000 subscribers for Wind Surfing magazine. She chooses the first 100 of the 5,000 names, this is clearly a convenient sample since the sample is easily, readily and conveniently available.

If she had selected 100 names randomly then it would have been called random sampling but in this case, she simply selected the first 100 names for the sake of convenience therefore, it is a convenience sample.

Further more explanation:

▪️ $\blue{ \mathsf{ {What \: is \: Work \: ?}}}$

⇒Work done by a force acting on a body is defined as the product of force and displacement of the body in the direction of the force.

▪️ $\blue{ \bold{ \sf{What \: is \: SI \: unit \: ?}}}$

⇒The system of units which is agreed by the international convention of scientists held in France in 1960 is called SI unit.

▪️ $\blue{ \bold{ \sf{What \: do \: you \: mean \: by \: \: one \: joule \: work \: \: ?}}}$

⇒One joule is the amount of work done when one Newton force displaces a body through one metre in its own direction.

Hope I helped!

Isaac, a manager at a supermarket, is inspecting cans of pasta to make sure that the cans are neither dented nor have other defe

Fynjy0 [20]

Answer:

0.0064 is the probability that Isaac will find his first defective can among the first 50 cans.

Step-by-step explanation:

W are given the following in the question:

Probability of defective can =

$P(A) = \dfrac{1}{90}$

We have to find the probability that Isaac will find his first defective can among the first 50 cans.

Then the number of adults follows a geometric distribution, where the probability of success on each trial is p, then the probability that the kth trial (out of k trials) is the first success is

$P(X=k) = (1-p)^{k-1}p$

We have to evaluate:

$P(x = 50)\\= (1-\frac{1}{90})^{50-1}(\frac{1}{90})\\= 0.0064$

0.0064 is the probability that Isaac will find his first defective can among the first 50 cans.
