If the confidence level is increased from 90% to 99% for an SRS of size n , the width of the confidence interval for the mean μ
katrin2010 [14]

Answer:

If the confidence level is increased from 90% to 99% for an SRS of size n , the width of the confidence interval for the mean μ will <u>increase</u>.

Step-by-step explanation:

We have been given an incomplete statement. We are supposed to complete the given statement.

If the confidence level is increased from 90% to 99% for an SRS of size n , the width of the confidence interval for the mean μ will:

We know that when confidence level decreases from a value to a lower value, then the confidence interval for the mean decreases.

When confidence level increases from a value to a higher value, then the confidence interval for the mean increases.

When we will increase the confidence level from 90% to 99%, the width of the confidence interval for the mean will also increase, so it will become wider.

Therefore, the correct word for our given statement is increase.

Two ocean beaches are being affected by erosion. The table shows the width, in feet, of each beach measured at high tide where 1
Rudiy27

Answer:

Step-by-step explanation:

1. Erosion patterns

(a) Western Beach

In 15 yr, Western Beach erodes from 100 ft to 70 ft.

The rate of erosion is 30 ft/15 yr = 2 ft/yr.

(b) Dunes Beach

In 15 yr, Dunes Beach builds up from 20 ft to 95 ft.

The rate of buildup is 75 ft/15 yr = 5 ft/yr.

Beaches with equal width

The western beach loses 2 feet each year, every 5 years the beach loses 10 feet. Dunes beach gets 5 feet every year, and every 5 years the beach loses 25 feet.

2.From the table, it appears that the beaches will have the same width sometime in year 11 (2006).

wester beach at 11 years it was 78.

dunes beach it was 75.

and these are the most closest value beatween two  beaches

3. even if the rate remains constant we wont be able to have same width . because the width of weatern beach is decreasing and dunes beach is increasing. so the year their width was almost equal was year 11th. they will never have the same width because western beach is going down in width and dunes is going up.

hope it helps.  hope i get brainlist
