Answer: 0.05
Step-by-step explanation:
Given : To ensure the quality of the shipment, he selected a random sample of 300 cups and inspected them for defects. He found 15 to be defective.
i.e. sample size : n= 300
sample proportion : 
The best estimate for population proportion is the sample proportion.
Therefore, the estimated proportion defective in the population : 0.05
Answer:
d is the answers for the question
Step-by-step explanation:
please give me brainlest
Two point form:
y-(-7)/3-(-7)=x-6/-6-6
Rearrange to get y=-5/6x -2 (slope intercept form)
or y= 5x+6y=-12 (standard form)
Answer:
Yes, There is significant difference.
Step-by-step explanation:
Null Hypothesis , H0 : Mean income = 15000
Alternate Hypothesis , H1 : Mean income ≠ 15000
t = (x - u) / ( s / √n)
x = sample mean = 14500 here, u = population mean = 15000 here , s = standard deviation = 975 here , n = sample size
t = (14500 - 15000) / (975 / √169)
-500 / 75 = - 6.66
As calculated t value in absolute terms is > 1.96 , ie tabulated value at 95% significance level (two sided). So we reject the null hypothesis in favor of alternate hypothesis. Hence, we state that 'Mean Income ≠ 15000'
Answer:
Use a calculator to divide the two values (small over big) to get 14/35 = 0.4
Now multiply that result by 100 to convert to a percentage
0.4*100 = 40%
he has ridden 40% of the course so
