Prior to adding 75, the original data has a mean of 41/6 =6.833 & a median of 8

After adding the 75, the mean becomes 116/7 = 16.571 & the median = 9

So the median increased slightly (from 8 to 9) & the mean increased more quickly (from 6.833 to 16.571)

So it's C :The median increases less than the mean increases.

Based on the Nielsen ratings, the local CBS affiliate claims its 11:00 PM newscast reaches 41 % of the viewing audience in the a
Fantom [35]

Answer:

null hypothesis is p=0.41

alternate hypothesis is p<0.41

Sample proportion is 0.36

critical value for a = 0.01 is -2.2326

z-statistic is −1,0166

critical value for the level of significance 0.10 is -1.28155

we fail to reject the null hypothesis in 0.01 significance level.

Step-by-step explanation:

Let p be the proportion of the viewing audience of 11:00PM CBS newscast in the area. Then

H_{0}: p=0.41

H_{a}: p<0.41

Sample proportion is 0.36 and critical value (left tailed) for a=0.01 is -2.2326

sample proportion Z-score can be calculated as follows:

z(0.36)=\frac{p(s)-p}{\sqrt{\frac{p*(1-p)}{N} } } where

  • p(s) is the sample proportion of vieved newscast (0.36)
  • p is the proportion assumed under null hypothesis. (0.41)
  • N is the sample size (100)

putting the numbers z(0.36)=\frac{0.36-0.41}{\sqrt{\frac{0.41*0.59}{100} } } =−1,0166

if the level of significance is 0.10 then critical value would be -1.28155.

in 0.01 significance level sample mean is not in the critical region, therefore we fail to reject the null hypothesis.

Solve the equation or inequality 3/2t-16=4/3t-6
Tamiku [17]

Answer:

<em>t=60</em>

Step-by-step explanation:

3/2t-16=4/3t-6

(subtract 4/3t from both sides)

3/2t-16-4/3t=-6

(add 16 to both sides)

3/2t-4/3t=-6+16

(simplify)

1/6t=10

(divide by 1/6 (or multiply by 6 on both sides)

t=60
