A study was completed in Florida. In southern Florida, the study involved 3,000 patients; 54% of them experienced flulike sympto

ms during the same month. The study had a margin of error of 1.8%. What does that mean for the study? The confidence interval is between 52.2% and 55.8%. The confidence interval is between 50.4% and 57.6%. The confidence interval is between 53% and 55%. The confidence interval is between 30% and 97.2%.

Answer:

A (52,2%, 55,8%)

Step-by-step explanation:

To get the confidence interval, we have to add the margin of error to the point estimator.

The middle of the interval is 54%, and the ME is 1.8%. Don't forget that this means ±1.8%!

54 - 1.8 = 52.2%

54 + 1.8 = 55.8%

So our confidence interval is (52,2%, 55,8%) and the answer is A.

Standard form of a line passing through points (1, 3) and (-2, 5)
____ [38]

Answer:

<h2>2x + 3y = 33 </h2>

Step-by-step explanation:

As we move from (-2, 5) to (1, 3), x increases by 3 and y decreases by 2.

Hence, the slope of this line is m = rise / run = -2/3.

Start with the slope-intercept form y = mx + b.

Substitute 3 for y and 1 for x and -2/3 for m:

3 = (-2/3)(1) + b.

Remove fractions by mult. all three terms by 3:

9 = -2 + b, so b = 11, and y = (-2/3)x + 11

Again, mult. all three terms by 3:

3y = -2x + 33, or, in standard form,

<h2>2x + 3y = 33 </h2>

Is it more difficult to run up a ramp with a slope of 15 or a ramp with a slope of 5? Explain.
notsponge [240]

Answer:

the slope of 15 is more difficult to run on

Step-by-step explanation:

The larger the slope, the steeper the ramp.  A slope of zero is a horizontal line, which would be relatively easy to run on.  A slope of undefined is a wall, which we cannot run on (we would fall off).   The larger the number, the steeper it gets

a specification for bottle filling has an upper limit of 9.16 ounces and a lower limit of 9.12 ounces. the process is stabilized
ivanzaharov [21]

Answer:

Process Capability ratio / Index = 0.133

Step-by-step explanation:

From the question, we are told:

Upper limit of 9.16 ounces

Lower limit of 9.12 ounces

Process width of 0.05 ounces.

what is the process capability ratio

Process Capability ratio or Index formula

= Cp = (USL - LSL)/(6 × Standard deviation)

Cp = 9.16 - 9.12/6 × 0.05

Cp = 0.04/0.3

Cp = 0.13333333333

Approximately = 0.133
