Anika [276]

Answer: (110.22, 125.78)

Step-by-step explanation:

The confidence interval for the population mean is given by :-

$\mu\ \pm z_{\alpha/2}\times\dfrac{\sigma}{\sqrt{n}}$

Given : Sample size = 463

$\mu=118\text{ minutes}$

$\sigma=65\text{ minutes}$

Significance level : $\alpha=1-0.99=0.01$

Critical value : $z_{\alpha/2}=z_{0.005}=\pm2.576$

We assume that the population is normally distributed.

Now, the 90% confidence interval for the population mean will be :-

$118\ \pm\ 2.576\times\dfrac{65}{\sqrt{463}} \\\\\approx118\pm7.78=(118-7.78\ ,\ 118+7.78)=(110.22,\ 125.78)$

Hence, 99% confidence interval for the mean study time of all first-year students = (110.22, 125.78)

SOVA2 [1]

Answer:

Step-by-step explanation:

1) About how much medicine did he make in grams?

Dr. Mann mixed

9.357 g of chemical A,

12.082 g of chemical B,

7.502 g of chemical C

We can determine total amount of medicine that was prepared by Dr. Mann by summing up the chemicals (A,B,C)

=( 9.357grams of A + 12.082grams of B+ 7.502grams of C)

= 28.941 grams in total

The next step is to round up those chemicals value to their nearest tenth as asked by question

Dr. Mann mixed

9.357 g of chemical A= 9.4grams

12.082 g of chemical B,=12.1grams

7.502 g of chemical C =7.5grams

2)Estimate the amount of each chemical by rounding to the nearest tenth of a gram before finding the sum.

Then the sum after rounding up to nearest tenth is

(9.4grams +12.1grams + 7.5grams)

=29 gram

If a train travels at 80 mph for 12 min, what is the distance traveled?

AnnyKZ [126]

Answer:

<h2>ANSWER→ </h2>

16 miles
12 minutes is 1 /5 of a hour
80 ÷ 5 is 16
or 80x 1.466 =117.28 ft per second
12 minutes x 60 seconds is 720
117.28× 720= 84,441.6
84441.6÷ 5280= 15.992 miles.
