Answer:
Step-by-step explanation:
A Chi-square test is used to test the test of independence between rows and columns, contingency tables. It is a test related to frequencies. The observed frequency is a given statistical frequency known as the actual frequency, the expected frequency is known as the theoretical frequency is derived from the study by using the sum total of the row and total in the column divided by their corresponding sample size.
Answer:
Hello a value is missing in your question below is the value
samples of n = 10
answer : 24.63 < μ < 25.370
Step-by-step explanation:
Given :
Sample size = n = 10
Z∝/2 = Z0.0256 = 1.95
next calculate for margin of error
E = Z∝/2 * ( 0.6 / / 
)
= 0.370
therefore at 94.87% confidence interval the estimated population mean is
x - 0.370 < μ < x + 0.370
25 - 0.370 < μ < 25 + 0.370
24.63 < μ < 25.370
Answer:
no
Step-by-step explanation:
3 is the x coordinate/ integer and -4 is the y coordinate and the integer so it wouldn't make sense
x= 3 is a solution
and id you don't understand the first thing i said watch this
#1. 3, - 4
#2. x= - 4
#3. substitute/replace the x with what the x coordinate is
#4. it will be 3= - 4
#5. as you can see the numbers don't equal each other so it's a no solution
