Answer: No, the data provided is not sufficient evidence to conclude that the mean height of women in the city differs from the national mean.
Step-by-step explanation:
Since we have given that
Mean height = 61.5 inches
Standard deviation = 4.4 inches
n = 100
So, test statistic value would be
At 10% level of significance, in two tail test ,
z = 1.28
Since 1.28 > -2.727
So, we will accept the null hypothesis.
Hence, No, the data provided is not sufficient evidence to conclude that the mean height of women in the city differs from the national mean.

Answer:
Option (C) Miguel's daily wage=$70
Step-by-step explanation:
This can be expressed as;
Total amount a week=Amount he earns per day×number of days he works in a week
where;
Total amount a week=$490
Amount her earns per day=x
Number of days in a week=7 days, since wages are paid weekly even on days that Miguel does not go to work, like weekends.
replacing;
490=x×7
x=490/7
x=70
Miguel's daily wage=$70
Answer:
1) C
2)C
3)B
4)A
Step-by-step explanation:
1) Circle
Solve for area
A≈28.27cm²
d=Diameter 6cm
Using the formulas
A=πr2
d=2r
Solving for A
A=1
4πd2=1
4·π·62≈28.27433cm²
2)
To calculate 5% of a number, simply divide 10% of the number by 2. For example, 5% of 230 is 23 divided by 2, or 11.5.
