Last week, a GameStop store sold some $43 games and some $30 games for a total of
Vesnalui [34]

Answer: The total number of games sold by the GameStop is 14. That is 5 games of $43 and 9 games of $30.

Step-by-step explanation:

Considering some games of $43 were sold and others for $30 were also sold in arriving at the total of $485 sold.

If 5 games of $43 were sold it gives $215.

To get the difference, you subtract the amount sold for $43 from the total.

$485 - $215 = $270

To arrive at how many $30 games were sold;

$270 ÷ $30 per game = 9 games

Therefore, 5 games of $43 combined with 9 games of $30 gives a total of 14 games.

Fifty-six percent of Internet users have seen an online group come together to help a person or community solve a problem wherea
Lera25 [3.4K]

Answer:

95% confidence interval for the proportion of internet users who say online groups have helped solved a problem is between a lower limit of (0.65 - 0.9349/√n) and an upper limit of (0.65 + 0.9349/√n).

Step-by-step explanation:

Confidence interval for a proportion is given as p +/- margin of error (E)

p is the proportion of internet users who say online groups have helped solved a problem = 65% = 0.65

Let the number of internet users be represented by n

confidence level (C) = 95% = 0.95

significance level = 1 - C = 1 - 0.95 = 0.05 = 5%

critical value corresponding to infinity degrees of freedom and 5% significance level is 1.96

E = critical value × sqrt[p(1-p) ÷ n] = 1.96 × sqrt[0.65(1-0.65) ÷ n] = 1.96 × sqrt(0.2275 ÷ n) = 1.96×0.477/√n = 0.9349/√n

Lower limit of proportion = p - E = 0.65 - 0.9349/√n

Upper limit of proportion = p + E = 0.65 + 0.9349/√n

95% confidence interval is (0.65-0.9349/√n, 0.65+0.9349/√n)
