What is the best estimate for the sum of fractions 5//6 and 5/8

7nadin3 [17]

Answer:

The answer is 25/24 or 1.041

Step-by-step explanation:

Given 5/6 and 5/8, you can't find the sum at that point. This means we will have to find a common denominator, which will be 24.

6 x 4 = 24 and 8 x 3 = 24

Doing this, you will have to multiply the numerator and denominator by the value the denominator needs to be multiplied by to get 24.

5/6 x 4/4 = 20/24 and 5/8 x 3/3 = 15/24

After getting these values, you can then add them.

20/24 + 15/24 = 25/24 or 1.041

A national survey interviewed 3800 people ages 18 and older nationwide by telephone. One question asked was the amount of gasoli

NeTakaya

Answer:

For this case a parameter represent the population data and for this case the parameter would be the true mean $\mu$ who represent the amount of gasoline they used in the previous week

$\bar X= \frac{\sum_{i=1}^n X_i}{3800} =11.75$

And the sample mean is an unbiased estimator of the true mean.

Step-by-step explanation:

For this case a parameter represent the population data and for this case the parameter would be the true mean $\mu$ who represent the amount of gasoline they used in the previous week

And in order to estimate the parameter of interest we use a survey of n =3800 and the sample mean who represent an statistic is given by:

$\bar X = \frac{\sum_{i=1}^n X_i}{n}$

And we got:

$\bar X= \frac{\sum_{i=1}^n X_i}{3800} =11.75$

And the sample mean is an unbiased estimator of the true mean.
