Answer:
1.070,0.1003
Step-by-step explanation:
Given that a random sample of n=1400 registered voters and found that 720 would vote for the Republican candidate in a state senate race.
p = the proportion of registered voters who would vote for the Republican candidate.
Sample proportion =
Hypotheses are:
(Right tailed test )
p difference =
Assuming null hypothesis to be true,
Std error =
a) Test statistic Z = p difference/std error = 1.070
b) When z =1.28, p value = 0.100273
Answer:
The student must get at least 86 in the next text in order to get an upper A average.
Step-by-step explanation:
The scores in the three tests are: 91, 94 and 89
The average score here is = 91 (rounded off to nearest whole number)
In order to get an Upper A average after tackling the next test, the students total score in the four tests must be 90 × 4 = 360
Let's say the student scores x in the fourth test.
Then; 91 + 94 + 89 + x ≥ 360
274 + x ≥ 360
x ≥ 360 - 274
x ≥ 86
