The lengths of text messages are normally distributed with a population standard deviation of 4 characters and an unknown popula
umka21 [38]

Answer:

The answer is "(25.32, 30.68)"

Step-by-step explanation:

Given:

\bar x = 28\\\\ \sigma = 4\\\\n =26\\\\

When 98\% confidence level so, the z:

\alpha = 1 - 98\% = 1 - 0.98 = 0.2\\\\\frac{\alpha}{2} =\frac{0.02}{2} = 0.01\\\\Z_{\frac{\alpha}{2}} = Z_{0.01} = 1.645\ \ \  ( Using \ z \ table )\\\\

E = Z_{\frac{\alpha}{2} \times ( \frac{\sigma}{\sqrt{n}})  

= 1.645 \times (\frac{4}{\sqrt{26}})\\\\=2.68

When  98% confidence interval estimate of the population mean  is,

\bar x - E < \mu < \bar x + E\\\\28 - 2.68 <  \mu < 28 + 2.68\\\\25.32 <  \mu < 30.68\\\\(25.32,  30.68)\\\\

Given the figure below, find the values of x and z.
aleksandrvk [35]

Answer: x = 2 and z=78

Step-by-step explanation:

Opposite angles are non-adjacent angles formed by two intersecting lines. Opposite angles are congruent (equal in measure). Z is Opposite to 78 angle, so z=78.

Adjacent angles add up to 180 degrees, and 78 and (5x + 92) are adyacents so:

5x + 92 + 78 = 180

5x + 170 = 180

5x = 180 - 170

5x = 10

x = 10/5

x = 2
