RSW $38\mathrm{.}59\mathrm{.}7$ in the U$.$S$.$ Answer the following questions.

ORD $55\mathrm{.}68\mathrm{.}2$

SNA $22\mathrm{.}47\mathrm{.}1$ Number Question Answer

MEM $14\mathrm{.}114\mathrm{.}41$ Produce a histogram of AT&T speeds. Place it to the right. Include a title.

MKE $23\mathrm{.}113\mathrm{.}42$ Calcualte the Median of internet speed for Verizon $13\mathrm{.}9$

IND $24\mathrm{.}530\mathrm{.}63$ Calcualte the Median of internet speed for AT&T $8\mathrm{.}7$

DCA $6\mathrm{.}514\mathrm{.}44$ Calcualte the Mean of internet speed for Verizon $17\mathrm{.}6$

LAS $21\mathrm{.}5175$ Calcualte the Mean of internet speeds for AT&T $10\mathrm{.}7$

CMH $25\mathrm{.}73\mathrm{.}86$ Calcualte the Standard deviation of internet speeds for Verizon $16\mathrm{.}0$

PIT $14\mathrm{.}712\mathrm{.}47$ Calcualte the Standard deviation of internet speeds for AT&T $8\mathrm{.}1$

ATL $77\mathrm{.}833\mathrm{.}9$

MDW $71\mathrm{.}35\mathrm{.}5$ Question $8$

BWI $4312\mathrm{.}78$ Can we claim that the two internet providers have equal speeds in average? Null Hypothesis : Verizon and AT&T have equal wireless data coverage at U$.$S$.$ airports.

Alternative Hypothesis : Verizon and AT&T have different wireless data coverage at U$.$S$.$ airports.

RDU $20\mathrm{.}211$ Perform the test to verify $($and support$)$ your answer. $($Please specify the null Perform t$.$test $0\mathrm{.}008286955$

FLL $15\mathrm{.}54\mathrm{.}8$ and alternative hypothesis and explain how you interpret the result of the test$)$ Less or bigger than $0\mathrm{.}05?$ Less than $0\mathrm{.}05$

SMF $13\mathrm{.}717\mathrm{.}59$ What is the correlation coefficient between AT&T and Verizon speeds. What Decision: Reject

SEA $11\mathrm{.}18$ does this correlation coefficient mean $($i$.$e$.$ do speeds tend to move in same Interpert: Verizon and AT&T have different wireless data coverage at U$.$S$.$ airports.

IAD $13\mathrm{.}514\mathrm{.}7$ or opposite dirrecrions$)?$ How strong is the relationship?

MCI $10\mathrm{.}29\mathrm{.}5$

LGA $21\mathrm{.}113\mathrm{.}8$

CLE $15\mathrm{.}17\mathrm{.}6$ Question $9$

MCO $14\mathrm{.}29\mathrm{.}5$ Correlation? $0\mathrm{.}368090172$

PDX $4\mathrm{.}56\mathrm{.}5$ Correlation coeffcient? Speed tend to move in the same dirrections

CLT $7\mathrm{.}99\mathrm{.}1$ How strong is the relationship? Weak positive correlation.
