Answer:
Statements I and II
Step-by-step explanation:
In Statistics, parameter is any numerical value that characterizes a population while statistics are numerical values that characterizes a sample from a given population.
Statistics are most often used to estimate the population parameters
For example the sample mean is a statistic and the population mean is a paranmeter
The mean SAT score of all students from New York is the parameter.
The mean SAT score of 105 students from New York is called the statistic.
The correct choice is the third option.
Pretty simple. He needed 6.7 gallons to fill the tank. At 3.80/gallon, he spent $25.46
Answer:
$0.03
Step-by-step explanation:
The 1.4% interest rate given is an annual rate. So, the daily interest rate is 1/365 of that value. The first day's interest is 1/365 of 1.4% of $720:
1/365 × 0.014 × $720 ≈ $0.0276 ≈ $0.03 . . . . first day's interest
Μ = 500, population mean
σ = 110, population stadard deviation
The given table is
z 0.00 0.25 0.35 0.45 1.00 1.26 1.35 1.36
P 0.5000 0.5987 0.6368 0.6736 0.8413 0.8961 0.9115 0.9131
Range of random variable is X = [350, 550].
Calculate z-score for x = 350.
z = (350 - 500)/110 = -1.364
From the given tables,
The probability at x = 350 is
1 - 9131 = 0.0869
Calculate the z-score for x = 550.
z = (550 - 500)/110 = 0.454
From the given tables,
The probability at x = 550 is 0.6736
The probability that x =[350,550] is
0.6736 - 0.0869 = 0.5867
Answer: 0.5867 (or 58.7%)
Answer:
pretty sure its 1/12
Step-by-step explanation:
on two six sided dices I know that the probability of ten is 3/36. When you simplify that you get 1/12
