In a survey of 400 households, just 40 said they regularly purchased grits. A statistician used Agresti's shrinkage estimator (a Bayesian estimator) to find the 95% confidence interval of the proportion. What was his estimate?

a. 0.100 ± 0.0294
b. 0.100 ± 0.0152
c. 0.104 ± 0.0298
d. 0.100 ± 0.05
e. 0.100 ± 0.0152

wholesale price is the initial price before markup. retail price comes after the markup.

a price of 8 bucks that's marked up by 100%   is

formula: initial price + (percent markup in fraction/decimal)(initial price)

8+(1)(8)

8+8

16

retail price is $16.

3-4

step-by-step explanation:

the answer is 3-4 because both 45 and 60 has a multiple of 15.

45/3=15

60/4=15

therefore the odds against selecting a red is 4-3

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:

yes.. it's proven to be 36.
