A meteorologist is studying the speed at which thunderstorms travel. A sample of 10 storms are observed. The mean of the sample

dezoksy [38]

Answer:

The 95% confidence interval for the true mean speed of thunderstorms is [10.712, 13.688].

Step-by-step explanation:

Given information:

Sample size = 10

Sample mean = 12.2 mph

Standard deviation = 2.4

Confidence interval = 95%

At confidence interval 95% then z-score is 1.96.

The 95% confidence interval for the true mean speed of thunderstorms is

$CI=\overline{x}\pm z*\frac{s}{\sqrt{n}}$

Where, $\overline{x}$ is sample mean, z* is z score at 95% confidence interval, s is standard deviation of sample and n is sample size.

$CI=12.2\pm 1.96\frac{2.4}{\sqrt{10}}$

$CI=12.2\pm 1.487535$

$CI=12.2\pm 1.488$

$CI=[12.2-1.488, 12.2+1.488]$

$CI=[10.712, 13.688]$

Therefore the 95% confidence interval for the true mean speed of thunderstorms is [10.712, 13.688].

Area of trapezoids <br>find the area

Zinaida [17]

Answer:

Area of the trapezoid = $6cm^2$

Step-by-step explanation:

Area of a trapezoid:

(1/2)*Sum of parallel opposite sides +Distance between the parallel sides

Parallel sides are: 2 cm and 4 cm

Distance between the parallel sides is 2 cm

Area of the trapezoid:

$=\frac{1}{2}*(2+4)*2\\\\=\frac{1}{2}* 6*2\\\\=\frac{12}{2}\\\\ =6cm^2$

Area of the trapezoid is $6cm^2$
