Answer:
(c) H0 should be rejected
Step-by-step explanation:
Null hypothesis (H0): population mean is equal to 5
Alternate hypothesis (Ha): population mean is greater than 5
Z = (sample mean - population mean) ÷ (sd/√n)
sample mean = 5.3, population mean = 5, sd = 1, n = 500
Z = (5.3 - 5) ÷ (1/√500) = 0.3 ÷ 0.045 = 6.67
Using the normal distribution table, for a one tailed test at 0.01 significance level, the critical value is 2.326
Conclusion:
Since 6.67 is greater than 2.326, reject the null hypothesis (H0)
The probability of spinning a prime number and not flipping heads will be given as follows:
P(Prime)*P(Tails)
P(Prime)=3/5
P(Tails)=1/2
Thus
P(Prime) and P(Tails)
=3/5×1/2
=3/10
The digital time for quarter past three is 3:15, it is 15 minutes past 3 o'clock.
The midpoint of a line divides the line into equal segments.
The option that proves PQ = LO is (a)
The given parameters are:
P is the midpoint of LM.
So, we have:
Q is the midpoint of NO.
So, we have:
Distance PQ is calculated as follows:
This gives:
Distance LO is calculated as follows:
So, we have:
Thus:
Hence, the correct option is (a)
