A 48-year-old person is 4.2048 × 105 hours old. Write this number in standard form.
Fynjy0 [20]
4.2048 x 105 = 441.504

the standard form should be between 1 and 9 so the decimal point should be after the first digit (4)

it would look like this 4.41504 x 10 to the power of 2 because it moved back two places. hope it makes sense? (:

a) Suppose that a random sample of size 80 has a sample mean of 1.69 ppb and a sample standard deviation of 0.25 ppb. Find a 95%
lys-0071 [83]

Answer: The confidence interval is 1.69ppb±0.055

Step-by-step explanation:

To find the confidence interval, first find the z* which is the appropriate z*-value related to the confidence interval of preference. As in this is 95%, z*-value = 1.96 (Note: The value is from the standard normal Z distribution).

With the z*-value, multiply by the division of the standard deviation and the square root of the sample size:

z*-value . σ/√n = 1.96 · \frac{0.25}{\sqrt{80} } = 0.055

The 95% confidence interval of the sample mean of 1.69 ppb is 1.69ppb±0.055ppb
