Is this correct? (Last question) Btw giving BRAINLIEST (I'll try to) if you know little who little lad is BUT you have to say wh
at he says!!
1 answer:
The expression can be estimated by
, so the answer would be roughly 14 here. I'm not sure where you got that '1' from.
Directly below that problem, we have the expression which can be estimated by computing
which simplifies to 63. The '1' is from rounding to the nearest whole number.
Other than that, everything else looks correct on your worksheet.

Answer:
This means that the equation has infinitely many solutions.
Step-by-step explanation:
Say I have a problem like 1+x=1+x.
Subtracting 1 from both sides gives me x=x.
Any number can be x b/c any number equals itself.
You can prove this by checking: 4=4; 1=1; 1000=1000; -356=-356;
Any number will equal itself, so the equation has infinitely many solutions.

Answer:
The point estimate for the proportion is p = 0.4725
The 95% confidence interval for the proportion of non-fatal accidents that involved the use of a cell phone is (0.4236, 0.5214).
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of , and a confidence level of
, we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of .
For this problem, we have that:
Point estimate
95% confidence level
So , z is the value of Z that has a pvalue of
, so
.
The lower limit of this interval is:
The upper limit of this interval is:
The 95% confidence interval for the proportion of non-fatal accidents that involved the use of a cell phone is (0.4236, 0.5214).
