Answer:
0.07378
Step-by-step explanation:
We solve using z score formula
z = (x-μ)/σ/√n, where
x is the raw score = 65 inches
μ is the population mean= 64.5 inches
σ is the population standard deviation = 2.99
n = 75
z = 65 - 64.5 /2.99/√75
z = 0.5/0.345255461
z = 1.4482
Probability value from Z-Table:
P(x<25) = 0.92622
P(x>25) = 1 - P(x<25)
= 1 - 92622
= 0.07378
The probability that the mean height for the sample is greater than 65 inches is 0.07378
(a) 1
Explanation:
The mode of the data set is the number that occurs most frequently in the set. To easily find the mode. put the numbers in order from least to greatest and count how many times each number occurs. The number that occurs the most is the mode.
If 5 different numbers are there in a data set then, the mode would be 1 as a number is present minimum one number of times.
