Answer:

Answer:

Both centres are best described by the median.

Step-by-step explanation:

Here is a summary of the statistics from your data.

City      Min    Q1   IQR     Q3     Max     Median   Mean    σ    

Rome      0     3.60  8.65  12.25     16         8.25       7.99     5.20

NY           1      2.25  4.69   6.64     20        5.45       6.39     5.91

The box plots below show that both centres are best described by the median.

The outlier in the New York data greatly distorts the mean but does not affect the median. The mean without the outlier would have been 4.45.

Indicate whether the following analysis involves a statistical test. If it does involve a statistical test, state the population
eimsori [14]

Answer:

Yes, The analysis involves a statistical test.

The hypothesis are H_0: \mu_R = \mu_L,\ and\ H_A: \mu_R < u_L

Step-by-step explanation:

Consider the provided information.

Testing 500 right-handed participants on the reaction time of their left and right hands to determine if there is evidence for the claim that the right hand reacts faster than the left.

Yes, The above analysis involves a statistical test.

Where claim is right hand reacts faster than the left hand.

If right hand reacts faster that means the reaction time of right hand should be smaller than the reaction time of left hand.

Let \mu_R to be the average reaction time of their right hands for the right-handed participants and \mu_L to be the average reaction time of their left hands.

Therefore, the hypothesis are H_0: \mu_R = \mu_L,\ and\ H_A: \mu_R < u_L
