Excel computes a two‑sample confidence interval for the difference in proportions just as well and as easily as Minitab and othe

Mathematics
1 answer:
True [87]3 years ago
5 0

Answer:

See ecplanation below

Step-by-step explanation:

False.

On the Data analysis tool from excel we can conduct the following procedures:

Anova: Single Factor

Anova: Two factor with replication

Anova: Two factor without replication

Correlation

Covariance

Descriptive statistics

Exponential smoothing

F-test Two sample for Variances

Fourier analysis

Histogram

Moving Average

Random number generation

Rank and percentile

Regression

Sampling

t test: Paired two sample for means

t tes: Two sample assuming equal variances

t test: Two sample Assuming Unequal Variances

z test: Two sample for means

And as we can see we don't have an specific procedure just to obtain confidence interval for the difference of proportions. We need to remember that if we select a z test in excel, for example the output will contain the confidence associated to the parameter, but for this case is not too easy obtain a confidence interval for the difference of proportion like on a statistical software as (Minitab, R, SAS, etc) since all of these statistical softwares are elaborated in order to conduct all the possible statistical tests and confidence intervals for parameters of interest.

find the area of each sector. Use the 3.14 as the value of pi. Round your answer to the nearest tenth.​ Part 4
Yuri [45]

Answer:

1) 378.1 in²

2) 8.4 m²

Step-by-step explanation:

Area of sector= \frac{θ°}{360°}  \times \pi {r}^{2}

1) Area of sector

=  \frac{150°}{360°} \times 3.14 \times  {17}^{2}  \\  = 378.1 \: in^{2}  \\ (nearest \: tenth)

2) Area of sector

\frac{60°}{360°}  \times 3.14 \times  {4}^{2}  \\  = 8.4 \: m^{2}  \\ (nearest \: tenth)

if the sum of a number and nine is doubled, the result is seven less than the number. find the number.
avanturin [10]
X=the number we have to find.
This expression "2(x+9)" is when the sum of a number and nine is doubled.
If the result is seven less than the number, we will have: x-7

We can suggest the following equation:
2(x+9)=(x-7)
2x+18=x-7
2x-x=-7-18
x=-25

answer: the number would be:  -25.

What is the slope of a line that has an x-intercept of 6 and a y-intercept of 0
ankoles [38]

x intercept of 6 means (6,0) is on the line

y intercept of 0 means (0,0) is on the line

so the slope is (0-0)/(6-0) = 0

Answer: 0

Note: The question is actually bad; the line through the origin with slope zero is the X axis itself in which case it wouldn't be right to call the X intercept (just) (6,0).

Suppose that a random sample of size 64 is to be selected from a population with mean 40 and standard deviation 5. (a) what are
Vika [28.1K]
The sample mean is equal to the population mean.
\bar{X}=\mu=40
The standard deviation of X-bar (the standard error) is:
S.E.=\frac{\sigma}{ \sqrt{n} }=\frac{5}{\sqrt{64}}=0.625
