-7= z/-6 what does z equal

Mathematics
1 answer:
harina [27]2 years ago
7 0

Given:

- 7 =  \frac{z}{ - 6}

Taking -6 to the left side, we get in multiplication,

=  >  - 7 \times  - 6 = z

Now directly multiply and neglect the minus sign, as in multiplication, -sign \times -sign =  +sign

=  > 42 = z

So, value of z is <u>42</u>

Use the given level of confidence and sample data to construct a confidence interval for the population proportion p.
Molodets [167]

Answer:

The 95% confidence interval for the population proportion is (0.778, 0.884).

Step-by-step explanation:

We have to calculate a 95% confidence interval for the proportion.

The sample proportion is p=0.831.

 

The standard error of the proportion is:

\sigma_p=\sqrt{\dfrac{p(1-p)}{n}}=\sqrt{\dfrac{0.831*0.169}{195}}\\\\\\ \sigma_p=\sqrt{0.00072}=0.027

The critical z-value for a 95% confidence interval is z=1.96.

The margin of error (MOE) can be calculated as:

MOE=z\cdot \sigma_p=1.96 \cdot 0.027=0.053

Then, the lower and upper bounds of the confidence interval are:

LL=p-z \cdot \sisgma_p = 0.831-0.053=0.778\\\\UL=p+z \cdot \sisgma_p = 0.831+0.053=0.884

The 95% confidence interval for the population proportion is (0.778, 0.884).
