Answer:

Sweater is least expensive in City C with 2.9% sales Tax

Cost of Sweater in city B is $31.23

Step-by-step explanation:

Cost of a sweater = $30

Sales tax in city A= 3%

Cost in City A = $30 + ($30*3%)

= $(30 +0.9)=$30.9

Sales tax in City B = 4.1%

Cost in City B = $30+($30*4.1%)

= $(30+1.23)=$31.23

sales tax in city C = 2.9%

Cost in City C = $30+($30*2.9%)

=$(30+0.87)=$30.87

Refer to the technology output given to the right that results from measured hemoglobin levels (g/dL) in 100 randomly selected a

charle [14.2K]

Answer:

Step-by-step explanation:

Confidence interval in less than symbol expressed as

$\bar{x} - E < \mu < \bar{x} + E
$

Where $\bar{x}$ is sample mean and $E$ is margin of error.

$13.03 < \mu 13.42
$

The given t interval is $(13.032 , 13.418 )
$

That is $\bar{x} - E = 13.032$ and $\bar{x} + E = 13.418$

Solve these two equation by adding together.

$2 \bar{x} = 13.032 + 13.418
\\\\\bar{x} = 13.225$

Solve this value of \bar{x} in equation $\bar{x} - E = 13.032$ and solve for $E$

$13.225 - E = 13.032
\\\\E = 0.193
$

Best point estimate of $\mu = \bar{x} = 13.225
$

Best point estimate of margin of error = 0.193

Since sample size = 100 which is sufficiently large (Greater than 30) , it is no need to confirm that

sample data appear to be form a population with normal distribution.
