Answer:
H0 : μ = 1220
H1 : μ > 1220
Test statistic = 1.30
Step-by-step explanation:
Sample mean, x = 1235.91
Standard deviation, σ = 211.67
Sample size, n = 300
The hypothesis :
Null ; H0 : μ = 1220
Alternative ; H1 : μ > 1220
Tbe test statistic :
(x - μ) ÷ (σ/√(n))
(1235.91 - 1220) ÷ (211.67/√(300))
15.91 / 12.220773
= 1.3018
= 1.30
7*3=21....The first number they would both share would be 7
A=negative 1,020,000,000,000=407 to the 9th power of ten+337 to the 9th power of ten+276 to the 9th power of ten
*power of ten are exponents(negative numbers)
b=10,000,000=4 to the 6 power of ten+4 to the 6th power of ten+2 to the 6th power of ten
*power of ten are exponents( numbers are negative)
c=1,019,990,000,000
Y=9.5
Cause 4 times 9.5 is 38 minus 18 is 20
Answer:
The sum of four and the product of three and a number x is ...
Now we are dealing with an unknown figure,
x
The statement goes;
The sum of
4
and the product of
3
and a number
x
The word sum is represented by addition
The word product is represented by multiplication
Hence;
4
+
3
×
x
4
+
3 x → Statement
