Question

The data below shows the daily low temperatures, in degrees Fahrenheit, of a city for one week. Day Low Temperature, in Fahrenheit Monday 54.5 Tuesday 53 Wednesday 56.5 Thursday 54 Friday 52.5 Saturday 51 Sunday 53 The standard error of the sample mean for this set of data is __________. Answer choices are rounded to the hundredths place.

Answer 1

The standard error of the sample means for this set of data is 0.65.

Given that,

• The temperature is 54.5,53,56.5,54,52.5,51,53.
• And, the sample mean is 7.

Based on the above information

The mean should be

$= \frac{54.5+ 53+ 56.5 + 54+52.5+ 51+ 53}{7}$

= 53.25

And, the standard deviation is 1.7321

So, the standard error should be

= 1.73 ÷ √7

= 0.65

Therefore we can conclude that the standard error of the sample means for this set of data is 0.65.
