Answer:

A computer is a machine that accepts data as input, processes that data using programs, and outputs the processed data as information. Many computers can store and retrieve information using hard drives. Computers can be connected together to form networks, allowing connected computers to communicate with each other.

Thirty percent of a magazine's subscribers are female. A random sample of 50 subscribers Answer the following questions using Ex

Ann [662]

Based on the mean of the subscribers, the sample size, and the standard deviation, the probability of females being at most 0.25 is 0.2202.

The probability that they are between 0.22 and 0.28 is 0.2703.

The probability that they are within 0.03 of the population proportion is 0.3566.

<h3>What is the probability that they are at most 0.25?</h3>

Using Excel, we shall assume that the distribution is normally distributed.

We can therefore use the NORM.DIST function:

=NORM.DIST(0.25,0.3,0.0648,TRUE)

= 0.2202

<h3 /><h3>What is the probability that they are between 0.22 and 0.28?</h3>

=NORM.DIST(0.28,0.3,0.0648,TRUE) - NORM.DIST(0.22,0.3,0.0648,TRUE)

= 0.2703

<h3>What is the probability that they are within 0.03 of the population proportion?</h3>

X high = 0.30 + 0.03

= 0.33

X low = 0.30 - 0.03

= 0.27

= NORM.DIST(0.33,0.3,0.0648,TRUE) - NORM.DIST(0.27,0.3,0.0648,TRUE)

= 0.3566.

Building a linked list forward places the new item to be added at the beginning of the linked list.

LiRa [457]

Answer:

False

Explanation:

When a new item is added to a linked list it gets added to the rear end of the list.

For example if my list is as follows:

A->B->C

Now I want to add D, it will get added as follows:

A->B->C->D

Similarly if I add E, the updated list will become:

A->B->C->D->E
