Answer:
proportion of gamers who prefer console does not differ from 29%
Step-by-step explanation:
Given :
n = 341 ; x = 95 ; Phat = x / n = 95/341 = 0.279
H0 : p = 0.29
H1 : p ≠ 0.29
The test statistic :
T = (phat - p) ÷ √[(p(1 - p)) / n]
T = (0.279 - 0.29) ÷ √[(0.29(1 - 0.29)) / 341]
T = (-0.011) ÷ √[(0.29 * 0.71) / 341]
T = -0.011 ÷ 0.0245725
T = - 0.4476532
Using the Pvalue calculator from test statistic score :
df = 341 - 1 = 340
Pvalue(-0.447, 340) ; two tailed = 0.654
At α = 0.01
Pvalue > α ; We fail to reject the null and conclude that there is no significant evidence that proportion of gamers who prefer console differs from 29%

Answer:
45
Step-by-step explanation:
If you treat this as a ratio, it would be 3 vowels to every 7 tiles. If one value in the ratio is multiplied by a number, the other should be multiplied by the same number. So if there are 105 tiles, the 7 in the ratio was multiplied by 15. Multiply the other value, 3, by the same number and you get 45.
The number of black tokens in the bag. 8 green tokens; 4 for every 1 is 2 tokens
<h3>How to find the number of black tokens?</h3>
The number of green tokens in the bag and the ratio of green tokens to black tokens
We learn from the question that there are 8 green tokens in the bag, along with black tokens, in a container that also includes other tokens.
The ratio of green tokens to black tokens, according to what is further disclosed, is four to one.
The number of black tokens in the bag will be: since the black tokens are 4 and the green tokens are 4,
= 8/4
+ 2 tokens

She would have traveled 24 miles since from the house to the supermarket is 7 miles then from the supermarket to the municipal building is 5 miles then back 7 miles and then 5 miles. If you add all of that together then you will get 24 miles.
