Final shot john diggle needs to give up his trusted glock for a more non-lethal weapon. cisco ramon builds him a stun gun that his claims matches the glock shooting characteristics, including accuracy. do these data representing "shot groups" give statistically significant evidence of a difference in accuracy between the two types?
glock (cm): 9.3 16.7 7.1 14 5 6
stun gun (cm): 4.9 14.1 7 7.2 5.4 8.6
write the hypotheses:
h_0: the mean difference in between and is
h_a: the mean difference in between and is
are the conditions for inference met? (draw a picture of the histograms)
provide the calculations:
sample mean diff:
standard err:
t-stat:
p-value:
write your conclusion:
at the 5% level of significance, we that the mean difference in between and is we the mean difference in between and is [p-value = ]
construct a 90% confidence interval.
what does the interval mean in the context of the problem
we are 90% confident that the difference in mean
for is between and than
was cisco correct, does john’s stun gun perform the same? explain
show steps !

Arefrigeration system at your company uses temperature sensors fixed to read celsius (°c) values, but the system operators in your control room understand only the fahrenheit scale. you have been asked to make a fahrenheit (°f) label for the high temperature alarm, which is set to ring whenever the system temperature rises above –10°c. what fahrenheit value should you write on the label?
