Physicians at a clinic gave what they thought were drugs to 860 patients. Although the doctors later learned that the drugs were
Alexus [3.1K]

Answer:

Z=2.36

P=0.0091

Step-by-step explanation:

The hypothesis is:

π > 0.55 which is the population proportion

The formula to get the test statistic is

Zstat = P-π/√π(1-π)/n

P =507.4/860 = 0.59 (sample proportion )

n =860 (sample size)

π =0.55(population porportion)

Zstat = 0.59-0.55/√0.55(1-0.55)/860

Zstat =2.36

From Z table the probability of Z score of 2.36 is 0.9909

To calculate for P- value will then be

P= 1 - 0.9909

P= 0.0091

Which equation is an identity?
spayn [35]
7z + 10 - z = 8z - 2(z - 5)
7z + 10 - z = 8z - 2z + 10
6z + 10 = 6z + 10
6z - 6z = 10 - 10
0 = 0

Therefore, 7z + 10 - z = 8z - 2(z - 5)

The LATERAL Surface Area for the shape below is ____________. (assume the bases are the larger faces on the top and bottom.)
Zolol [24]

Answer:

LA=210\ cm^2

Step-by-step explanation:

we know that

The lateral area of the figure is given by

LA=Ph

where

P is the perimeter of the base (larger faces)

h is the height

Find the perimeter of the base P

P=2(11+10)=42\ cm

we have

h=5\ cm

substitute in the formula of lateral area

LA=42(5)=210\ cm^2
