Use the obtained rounded values in your calculations. Sample mean: 33.11 years (to 2 decimals) Sample standard deviation: 4.7468 years (to 4 decimals) -value: 0.154 (to 3 decimals) -value: (to 3 decimals) Because -value , we .

Answer:

The solution to these question can be defined as follows:

Step-by-step explanation:

H_0: \mu = 33 \ versus\\\\ H_a: \mu > 33\\\\\bar{X} = 33.11\\\\S = 4.7468\\\\n = 47\\\\df = n - 1 = 46\\\\\alpha = 0.05\\\\

Testing statistic:

t = \frac{(\bar{X} - \mu)}{[\frac{S}{\sqrt{(n)}}]}

= \frac{(33.11 – 33)}{\frac{4.7468}{\sqrt{47}}}\\\\= \frac{0.11}{0.6924}\\\\= 0.1589\\\\P-value = 0.4372\\\\P-value > \alpha = 0.05

Therefore the null hypothesis we do not deny, it is not clear enough so that the median age once British men get engaged is higher than in 2013.

nordsb [41]

Answer:

Step-by-step explanation:

2.99548 * 1.8342

the first number rounds to 3.....the second number rounds to 2.....3 * 2 = 6...but it will be a little short of 6 because of the 1.8.....so I am going with 5.5

===============================

jada ran 7.1 miles.....noah ran 5.123 miles

so jada ran (7.1 - 5.123) = 1.977 miles farther then noah

Mila [183]

The equation for this is quite simple. Take note x is the amount of shirts sold and 5.25 is the cost for each one to which they add a 75 setup fee.

So the equation will be

Composite figure is made up of 4 triangles and a square.

Area of Square = Length x Length 
Area of Square = 12 x 12
Area of Square= 144 cm²

Area of triangle = 1/2 x base x height
Area of triangle  = 1/2 x 12 x 8 
Area of triangle  = 48 cm²

Area of 4 Triangles = 48 x 4
Area of 4 Triangles = 192 cm²

Total Area = 144 + 192 = 336 cm² 

\Longrightarrow \boxed { \boxed { Answer : 336 cm^{2} }}
