A 95% confidence interval for the true proportion of women surviving their husbands is (0.561, 0.724). Recently a survey of 2,500 seniors receiving Social Security payments conducted by HHS reported that only 52.9% of women survived their husbands. Based on the confidence interval, is there sufficient evidence to suggest that the true proportion of women surviving their husbands is higher than 52.9%

i think 1: 2

step-by-step explanation:

so far i think you have the right thing going for you just remember soh cah toh

step-by-step explanation:

sine over hypotenuse

cosine   equals adjacent

tangent over hypotenuse

0.6, 3/5, and 6% are the 3 same portion.

but, when they're all changed to a decimal they would equal to 0.6.

hope this , good luck!

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:
