oee [108]

Answer:

An 99% confidence interval of the given proportion

(0.355 , 0.385)

Step-by-step explanation:

Given sample size n= 900

the number of successes in the sample is x=333

The proportion P = $\frac{x}{n} = \frac{333}{900} = 0.37$

Q = 1-P =1 - 0.37 = 0.63

Confidence interval:-

99% of confidence interval zα = 2.93

$(P - z_{\alpha } \sqrt{\frac{PQ}{n} } , P + z_{\alpha } \sqrt{\frac{PQ}{n} })$

$(0.37 - 2.93 \sqrt{\frac{0.37(0.63}{900} } ,0.37 +2.93 \sqrt{\frac{0.37(0.63}{900} } })$

(0.37 - 0.015 , 0.37 + 0.015)

(0.355 , 0.385)

Conclusion:-

An 99% Confidence interval (0.355 , 0.385)

A triathlon course includes a 400m swim,a 40.1km bike ride,and a 12.2km run what is the total length of the course

agasfer [191]

Convert the meter distance to KM so thaey are all the same measurement:

1 meter = 0.001 km

400 m x 0.001 m/km = 0.4 km

Now add all three distances:

Total distance = 0.4 + 40.1 + 12.2 = 52.7 km.

The answer is B.
