MArishka [77]

Answer:

3.06

Step-by-step explanation:

The correct answer is - 3.06

Reason -

For sample A :

mean, \bar{x_{1} } = 8.05          

Standard deviation, \sigma_{1} = 1.36          

Size, n_{1} = 50          

                 

For sample B :

mean, \bar{x_{2} } = 7.26          

Standard deviation, \sigma_{2} = 1.06          

Size, n_{2} = 38

Now,

\bar{x_{1} } - \bar{x_{2} }  = 8.05 - 7.26 = 0.79

Standard deviation error, SE = √(\sigma_{1}²/n_{1} + \sigma_{2}²/n_{2})  = 0.2580

Now,

Z-statistic = (\bar{x_{1} } - \bar{x_{2} } )/ SE

                = 0.79/0.2580

                = 3.06

⇒Z-statistic = 3.06

Does the frequency distribution appear to have a normal​ distribution? Explain. Temperature ​(degrees​F) Frequency 35 dash 39 1
AlexFokin [52]

Answer:

D. ​Yes, because the frequencies start​ low, proceed to one or two high​ frequencies, then decrease to a low​ frequency, and the distribution is approximately symmetric.

Step-by-step explanation:

Hello!

The given frequency distribution for temperatures.

To see if the distribution appears to have a normal distribution you have to draw a histogram using the information. Check attachment.

As you can see, the distribution appears symmetric, it starts low and proceeds to grow until it reaches its maximum point (f(4)=13) and then starts to decrease to low frequencies. The right tail decreases a little more than the left one but it is almost symmetrical.

I hope this helps!
