Two twin sisters, Gwen and Jackie, are both 20 years old in the year 2050. Jackie takes off on a round-trip to Vega, 25 light-ye

Contact [7]

Answer:

C. about 25 years.

Step-by-step explanation:

We have been given that two Jackie takes off on a round-trip to Vega, 25 light-years away. She travels at an average speed close to the speed of light, say, 0.9999c.

To find time it will take Jakie to reach Vega, we will divide the distance of Vega by Gwen's speed.

$\text{Time}=\frac{\text{Distance}}{\text{Speed}}$

$\text{Time}=\frac{25}{0.9999}$

$\text{Time}=25.00250$

$\text{Time}\approx 25$

Therefore, it will take approximately 25 years for Jakie to reach Vega and option C is the correct choice.

Correct answers:

$\left(241.42,\ 262.14\right)$

A 95% confidence interval for μ is (x¯−zα/2σn‾√,x¯+zα/2σn‾√). Here, α=0.05, σ=37, and n=49. Use Excel to calculate the 95% confidence interval.

1. Open Excel, enter the given data in column A, and find the sample mean, x¯, using the AVERAGE function. Thus, the sample mean, rounded to two decimal places, is x¯=251.78.

2. Click on any empty cell, enter =CONFIDENCE.NORM(0.05,37,49), and press ENTER.

3. The margin of error, rounded to two decimal places, is zα/2σn‾√≈10.36. The confidence interval for the population mean has a lower limit of 251.78−10.36=241.42 and an upper limit of 251.78+10.36=262.14.

Thus, the 95% confidence interval for μ is (241.42, 262.14).
