Kay [80]

-.12 to both sides
49.46+.2x = 55.96
-49.46 to both sides
.2x = 6.5
Divide by .2 on both sides
X= 32.5

starting at sea level a submarine descends at a constant rate to a depth of negative 5 6 Mile relative to sea level in 4 minutes

ycow [4]

Answer:

Step-by-step explanation:

To find how many miles the submarine is going per minute, you need to divide the miles (56) by the minutes (4)

56/4 =

14 miles per minute

If the submarine has been descending for 1 minute, and descends at 14 miles per minute, you can conclude that it wend 14 miles below sea level in 1 minute.

. The manager of a local small bank wants to estimate the average daily balance of all the checking accounts. Assume a random sa

MaRussiya [10]

Answer:

A 95% confidence interval estimate of the population mean (average) daily balance of all the checking accounts is $274.32 to $331.68

Step-by-step explanation:

Consider the provided information.

A random sample of 21 checking accounts at the bank are chosen,

That means n=21

df = n-1

df = 21-1=20

We need to Construct and interpret a 95% confidence interval.

Determine t critical value for 95% confidence interval.

0.95=1-α

α=0.05

The sample size is small and it is a two tailed test.

From the t value table confidence interval is 2.086

An average daily balance is $303 and a standard deviation of $63.

$CI=\bar x\pm t_c \times \frac{s}{\sqrt{n}}$

Substitute the respective values.

$CI=303\pm 2.086 \times \frac{63}{\sqrt{21}}$

$CI=303\pm 28.68$

$CI=274.32\ or\ 331.68$

A 95% confidence interval estimate of the population mean (average) daily balance of all the checking accounts is $274.32 to $331.68
