The data (1.5.8.5.1) represent a random sample of the number of days absent from school for five students at Monta Vista High. F
lianna [129]

Answer:

\bar X = \frac{1+5+8+5+1}{5}= \frac{20}{5}= 4

\sigma= \sqrt{\frac{(1-4)^2 +(5-4)^2 +(8-4)^2 +(5-4)^2 +(1-4)^2}{5}} =\sqrt{\frac{36}{5}}= 2.68

And based on this the best answer would be:

a. mean = 4; standard deviation = 2.68

Step-by-step explanation:

For this case we have the following data given:

1,5,8,5,1

We can find the sample mean with the following formula:

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

And replacing we got:

\bar X = \frac{1+5+8+5+1}{5}= \frac{20}{5}= 4

And for the deviation (assuming that the correct approximation is the deviation for a population) we can calculate the deviation with the following formula:

\sigma = \sqrt{\frac{\sum_{i=1}^n (X_i -\bar X)^2}{n}}

And replacing we got:

\sigma= \sqrt{\frac{(1-4)^2 +(5-4)^2 +(8-4)^2 +(5-4)^2 +(1-4)^2}{5}} =\sqrt{\frac{36}{5}}= 2.68

And based on this the best answer would be:

a. mean = 4; standard deviation = 2.68

Evgesh-ka [11]

Answer:

(Thermometer B reading - Thermometer A reading)

Step-by-step explanation:

The thermometer reading aren't given in the question.

However, hypothetically.

The difference between two temperature values (morning and evening values) would be :

Temperature in the evening - morning temperature

Therefore,

If ;

Thermometer A reading = morning temperature

Thermometer B reading = evening temperature

Difference in the temperature :

(Thermometer B reading - Thermometer A reading)
