The Tampa Times polled 1,457 adults in the city to determine whether they put on their shirt before they put on their pants. Of
Morgarella [4.7K]

Answer:

The mean is 0.32 and the standard deviation is 0.0122.

Step-by-step explanation:

Given that the Tampa Times polled 1,457 adults in the city to determine whether they put on their shirt before they put on their pants.

Of the respondents, 48% said they put their shirt on first.

32% of all adults actually put their shirt on first

i.e. sample proportion is 48% while population proportion is 32%

Hence sampling distribution follows a distribution with mean = population proportion p

Hence here mean = 0.32

Std deviation of sampling distribution = \sqrt{\frac{pq}{n} } =\sqrt{\frac{0.32(0.68)}{1457} } \\=0.0122

Hence option 3) The mean is 0.32 and the standard deviation is 0.0122.

is right

3x+5y=-3 x-5y=-5 show your work
frez [133]
We are given the equations 3x+5y=-3 and x-5y=-5.

Both equations have a 5y  term which allows us to easily solve the system by elimination. To do so we will add the equations together like a simple addition problem by adding the x terms together, the y terms together, and the integer answers together.

3x + 5y = -3
+x - 5y = -5
---------------
4x + 0y = -8

The y terms cancel out since one is positive and one is negative. Now we can solve for x.

4x = -8

\frac{4x}{(4)} = \frac{-8}{(4)}

x = -2

Now plug -2 in for x in one of the original equations to find y.

(-2) - 5y = -5

-5y = -3

y = 3/5

Our answer as an ordered pair is (2, 3/5)

Does the residual plot indicate that a line is a good model for predicting the height of girls from their ages? Explain.
galben [10]
A plot of residuals (vertical deviations from the regression line) shows the errors or lack of fit, so it would indicate a good fit if the residuals are small, vs. over fit if they are large. Due to age related growth short pre teen, and a plateau after age 21, I would expect a linear regression would offer estimate age 5.5 years.

Is 593 divide by 6 a little less than 10, a little more than 10, a little less than 100, or a little more than 100? Explain.
lesantik [10]
A little less than 100. 593 is 7 numbers away from 600, so if you divide 6 by 600 hundred the answer is 100. Since 593 is less than 600, the answer will be less than 100.
