First, we round 995:

We need to round it up since 995 has a 5 in the ones place and we always round 5-9 up.

995 is about 1000.

Then, we round 51:

51 is closer to 50 than 60.

51 is about 50.

The expression before: 995*51.

Now: 1000*50.

We annex the zeroes and that get us 1*5 = 5. Then, we add back the four zeroes:

1000*50 = 50000

So 995*51 is about 50,000.

995 x 51

995 = 1000

51 = 50

1000 x 50 = 50,000

Answer:

The value of the test statistic z for this hypothesis test is -2.79

Step-by-step explanation:

Consider the provided information.

To calculate the test statistic use the formula:

z=\frac{\hat p-p_0}{\sqrt{\frac{p_0(1-p_0)}{n}}}

Where, z  is Test statistics, n is Sample size, p₀ = Null hypothesized value  and \hat p = Observed proportion.

p₀ = 0.50

Thus 1-p₀= 0.50

42% responded that if they had a cell phone, thus \hat p=0.42

The sample size is 305.

Substitute the respective values in the above formula.

z=\frac{0.42-0.50}{\sqrt{\frac{0.50(0.50)}{305}}}

z=\frac{-0.08}{\sqrt{0.00082}}

z=-2.79

Hence, the value of the test statistic z for this hypothesis test is -2.79

Step-by-step explanation:

First off the underscore (_) but even if we get rid of that and we try to solve:

7+7

?

=

14−6+2(45+55−668)

and because of the equal sign

14≠−1128

False.

if you ment it differently a please let me know in the comments!!

Hope this helps!! If so please mark brainliest and rate/heart if it did!!
