The National Highway Traffic Safety Administration reported the percentage of traffic accidents occurring each day of the week.

Zigmanuir [339]

Answer:

Hence,

Test statistic $X^{2}$ = 9.269.

p value = 0.148

Sunday= 15.23%, Monday= 12.62%, Tuesday= 13.10%, Wednesday=11.67%,

Thursday= 13.10%, Friday= 16.19%, Saturday= 18.09%.

Step-by-step explanation:

relative observed Expected Chi square

Category frequency(p) $O_{i}$ Ei=total*p $(O-E)^{2}$ $R^{2}_{i} =(O_{i} -E_{i} )^{2} /E_{i}$

1 0.142857143 64.0 60.00 16.00 0.267

2 0.142857143 53.0 60.00 49.00 0.817

3 0.142857143 55.0 60.00 25.00 0.417

4 0.142857143 49.0 60.00 121.00 2.017

5 0.142857143 55.0 60.00 25.00 0.417

6 0.142857143 68.0 60.00 64.00 1.067

7 0.142857143 76.0 60.00 256.00 4.267

Total 1.000 420 420 556 9.269

Test statistic $X^{2}$ = 9.269.

p value = 0.148 from excel: chidist(9.269,6)

Percentage %= Frequency of traffic occur on category x 100 / Total number of frequency given.

Category Percentage%

Sunday 15.23%

Monday 12.62%

Tuesday 13.10%

Wednesday 11.67%

Thursday 13.10%

Friday 16.19%

Saturday 18.09%

Which relation is a function? Please help I need asap

Alisiya [41]

Answer:

Probably A, can't see all of D

Step-by-step explanation:

I can't see the last of D, so I will still try.

A function means that each x only goes to one y, but each y can have multiple xs going to it. If that's hard to understand, on the table, if you have two of the same xs on the x side, they HAVE to have the same y on the y side. Simple as that.

Right away, A looks right since it doesn't repeat anything on the x side, it has 4, 5, 6 and 7. Let's look at the others.

B repeats 3, but the ys are different, one has 10 and one has 30, so this isn't a function. They would both have to be 10 or 30 or some other number.

C repeats -5 and both have a different y, 2 and 3, so not a function

D I can only see the first two x entries so I can't be sure, so maybe you can tell. If there is any repeat int he x side and the corresponding y side isn't the same then it also isn't the function. i have to assume there is a repeat though.
