(a) Find a 90% confidence interval for the population mean price (per 100 pounds) that farmers in this region get for their wate

Anon25 [30]

Answer:

The margin of error (E) $=0.49$

Step-by-step explanation:

Given,

mean $\bar{x}=6.88$

standard deviation $\sigma=1.90$

sample size $n=41$

$90\% \quad \text{confidence interval}$

Critical value $=\frac{z_\alpha}{2}\quad \quad\quad[\because\;\alpha=1-\text{confidence interval}]$

$=1-0.90$

$\Rightarrow \alpha=0.1$

Critical value $=\frac{z_{0.1}}{2}$

$=z_{0.05}$

$=1.645$

The margin of error (E) $=\frac{z_\alpha}{2} \times\frac{\sigma}{\sqrt{n} }$

$=1.645\times\frac{1.90}{\sqrt{41} }$

$=0.49$

Hence, The margin of error (E) $=0.49$

Can u guys help me with these two problems?? for the first one I got 76 ,but I don't think is right.

Answer:

See below

Step-by-step explanation:

15)

In the right-angle triangle, once one of the angles is 44º, then, the unknown angle is $x$ .

$180 = 44 + 90 + x$

$180 = 134 + x$

$x= 46$

The angle $y$ of the other triangle plus the angle $x$ of the right-angle triangle is equal to 90º, therefore they are complementary angles.

So,

$90 = x + y$

$90 = 46 + y$

$y=44$

To find ?, we have

$180 = 58 + 44 +?$

$180 = 58 + 44 +?$

$? =78$

16)

The sum of the internal angles of the triangle with angles 50º and 25º is equal to 180º, therefore, the other angle is

$180 = x + 50 + 25\\180 = x+ 75\\x=105$

Once the angles are opposite, they are the same. For the triangle with the 36º angle, we have

$180 = 36 + 105 + y$

$180 = 141+ y$

$y=39$

$?=39$
