⦁ A total of 640 people voted in an election. The circle graph shows the results. ⦁ How many people voted for Goron? Show your w

Bezzdna [24]

Circle graphs or pie charts are used to represent data in percentages or proportions

192 voted for Goron
288 voted for Smith or Fishman

<h3>People that voted for Goron</h3>

The total number of votes is given as:

Total = 640

The circle chart is not given.

So, we make use of an assumed value

Assume 30% voted for Goron

The number of people would be:

Goron = 30% * 640

Evaluate

Goron = 192

Hence, 192 voted for Goron using the assumed value

<h3>People that voted for Smith or Fishman</h3>

Assume 45% voted for Smith or Fishman

The number of people would be:

Smith or Fishman = 45% * 640

Evaluate

Smith or Fishman = 288

Hence, 288 voted for Smith or Fishman using the assumed value

Divide and simplify 4/7÷(-11/2)

lys-0071 [83]

Answer: $-\frac{8}{77}$

Step-by-step explanation:

$\frac{\frac{4}{7} }{-\frac{11}{2} }$

Multiply by the reciprocal in order to get rid of the fraction in the denominator.

$\frac{\frac{4}{7} }{-\frac{11}{2} }*-\frac{2}{11}$

$\frac{4}{7}*-\frac{2}{11}$

$-\frac{8}{77}$

Use technology to find the P-value for the hypothesis test described below. The claim is that for a smartphone carrier's data

EastWind [94]

Solution :

The null and alternative hypothesis is given by

$H_0: \mu = 11$

$H_a: \mu \ne 11$

Assume that the level of significance, α = 0.05

The t-test statistics is, t = 1.484

Degree of freedom :

df = n - 1

= 14 - 1

= 13

The P-value is given by

P-value = 2P (T>|t|)

= 2P(T>|1.484|)

= 2P(T>1.484)

= 2(=T.DIST.RT(1.484,13))

= 0.05
