22. Awful accidents (a) State hypotheses for a significance test to determine whether first responders are arriving within 8 minutes of the call more often. Be sure to define the parameter of interest. (b) Describe a Type I error and a Type II error in this setting and explain the consequences of each. (c) Which is more serious in this setting: a Type I error or a Type II error

a) H0: Time for first responders arrival is  ≥ 8 min,  Ha: Time for first responders arrival is  < 8 min

b) Type I error: the arrival time is not greater than or equal to 8min

   Type II error: the arrival time is greater than or equal to 8min

c) Type I error

Explanation:

a) the parameter of interest is the time of arrival of first responders. The hypothesis will test the time of arrival of first responders. The null hypothesis will be that it is greater than or equal to 8 min and alternate hypothesis will be that it is less than 8 min

b) Type I error: rejection of true null hypothesis

   type II error: non-rejection of true null hypothesis

c)  Serious setting would be in type I error as it would cause more damage

    racial conflict and discrimination has existed ever since man learned to kill with rocks and bones. these conflicts arose from disputes between territory, power, wealth, religion, or simple difference. some of the most infamous racial disputes include slavery, the holocaust, and the civil rights movement.

    these listed disputes often resulted in casualties from all sides. riots, wars, imprisonment, and lynching are all commonly associated with racial conflict on severe levels.

      however, racism is an improving issue in recent decades. people are being more accepting and welcoming of diverse populations. though, the world isn't perfect and it will take much more time, if ever, until the world is rid of racism.
