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%
10.5+(10.5*.4)=10.5+(4.2)=14.7lbs after the first month

Answer: Option 'A' is correct.
Step-by-step explanation:
Since we have given that
The ocean floor directly beneath the boat is at a depth of = 180 meters
Submarine is at an elevation when it is above the ocean's surface = 2 meters
Total distance submarine needs to descends at a constant rate = 180+2=182 m
Rate of submarine descends = 0.4 meters per second.
Time taken by a scientist spend descending after boarding the submarine is given by

so, it must be less than 455 seconds.
therefore, it becomes x<455.
Hence, Option 'A' is correct.
