Answer:
C 37.5%
Step-by-step explanation:
There are 3 planets closer to the sun than mars
3/8 = .375
Changing to a percent
37.5% are closer to the sun than mars
Answer:
3
Step-by-step explanation:
Integers: 0, 1, 2, 3, 4
0 + 1 + 2 + 3 + 4 = 10
Answer:
The domain is (negative infinity, infinity) the range is [3. Infinity) y>=3
Step-by-step explanation:
The domain for all quadratic functions are (Negative infinity, infinity)
The range is the output values of the function 3, to infinity
Answer:
(A) T-stat = 1.82
(B) Critical value is 1.645
(C) Yes, there is sufficient evidence to reject the null hypothesis using a 0.05 significance level.
Step-by-step explanation:
(A) T-stat (z) = (sample mean - population mean) ÷ sd/√n
sample mean = 3850 bus miles
population mean = 3800 bus miles
sd = 275 bus miles
n = 100
z = (3850 - 3800) ÷ 275/√100 = 50 ÷ 275/10 = 50 ÷ 27.5 = 1.82
(B) The test is a one-tailed test. The critical value is obtained from the standard normal distribution table. The critical value using a 0.05 significance level is 1.645
(C) Null hypothesis: The bus mechanical reliability is 3850 bus miles.
Alternate hypothesis: The bus mechanical reliability is less than 3850 bus miles.
Conclusion:
There is sufficient evidence to reject the null hypothesis because the test statistic (1.82) is greater than the critical value (1.645)
