yKpoI14uk [10]

Answer:

Confidence Interval in 95% confidence level for the quality rating is (6.06,7.46)

Step-by-step explanation:

Confidence Interval can be calculated using the formula M±ME where

M is the mean of the sample
ME is the margin of error in a given confidence level

Using the sample obtained from 50 business travelers we get

Mean of the sample is 6.76
standard deviation of the sample is 2.526

Margin of error (ME) around the mean using the formula

ME= $\frac{z*s}{\sqrt{N} }$ where

z is the corresponding statistic in 95% confidence level (1.96)

s is the standard deviation of the sample (2.526)

N is the sample size (50)

Using the numbers in the formula we get:

ME= $\frac{1.96*2.526}{\sqrt{50} }$ ≈ 0.70

Then the confidence interval becomes 6.76±0.70

Jlenok [28]

Answer:

He have left 1250 milliliters of sport drink.

Step-by-step explanation:

Given:

Eduardo bought 2 litre sports drink for soccer practice during practice.

Eduardo drank 250 milliliters of sport drink then he drank another 1/2 liter.

Now, to find the milliliter of sport drink he have left.

Eduardo bought sports drink = 2 litre.

Now, to convert litre into milliliter by using conversion factor:

1 litre = 1000 milliliter.

2 liters = 2 × 1000 milliliters.

2 liters = 2000 milliliters.

Thus, Eduardo bought 2000 milliliters sport drink.

As, Eduardo drank 250 milliliters of sport drink.

So, to get the sport drink left after he drank we subtract 250 milliliters from 2000 milliliters:

$2000-250\\\\=1750\ milliliters.$

Thus, 1750 milliliters sport drink left.

Now, to get the sport drink left after he drank $\frac{1}{2} \ liter$ we subtract $\frac{1}{2} \ liter$ from 1750 milliliters:

$\frac{1}{2} \ liter =500\ milliliters.$

So,

$1750-500\\\\=1250\ milliliter.$

Therefore, he have left 1250 milliliters of sport drink.
