Answer:

1.The morning temperature was 6 degrees above the afternoon temperature.

Step-by-step explanation:

Given,

Morning temperature: +6°F

Afternoon temperature: 0°F

Night temperature: −2°F

∵ 6 > 0 > -2

i.e., Morning temp > Afternoon temp > Night temp

The difference between morning temp and afternoon temperature = 6° - 0° = 6°

Thus, morning temperature was 6 degrees above the afternoon temperature.

The difference between afternoon temp and night temp = 0° - (-2°)

= 2°

Thus, afternoon temperature was 2 degrees above the night temperature.

The difference between morning temp and night temp = 6° - (-2°)

= 8°

Thus, morning temperature was 8 degrees above the night temperature.

Karo-lina-s [1.5K]

Answer:

573-1.690\frac{22}{\sqrt{36}}=566.8033    

573+1.690\frac{22}{\sqrt{36}}=579.1967      

And the 90% confidence interval would be between [566.80 and 579.20]

Step-by-step explanation:

Information given

\bar X=573 represent the sample mean

\mu population mean (variable of interest)

s=22 represent the sample standard deviation

n=36 represent the sample size  

Confidence interval

The confidence interval for the mean is given by the following formula:

\bar X \pm t_{\alpha/2}\frac{s}{\sqrt{n}}   (1)

The degrees of freedom are given by:

df=n-1=36-1=35

The Confidence level is 0.90 or 90%, the significance would be \alpha=0.1 and \alpha/2 =0.05, and the critical value for this case would be t_{\alpha/2}=1.690

And replacing we got:

573-1.690\frac{22}{\sqrt{36}}=566.8033    

573+1.690\frac{22}{\sqrt{36}}=579.1967    

And the 90% confidence interval would be between [566.8033 and 579.1967]
