Answer:
Step-by-step explanation:
a) H0: 
Ha: 
(Two tailed test at 5% significance level)
b) n=30
Mean difference = 
Std error of mean = 
b) Test statistic t = mean diff/std error = -1.552
df = 30-1 =29
p value=0.0657
c) Since p > 0.05 our signi. level, we accept null hypothesis.
There is no significant difference between the means.
d) Using critical value we find that test statistic is > critical value left
So accept H0
Answer:
4 feets = 48 inches
2 miles = 10,560 feets
1 2/3 yards = 5 feets
3 1/2 yards = 126 inches
Step-by-step explanation:
Recall :
1 Feet = 12 inches
1 MILE = 5280 feets
1 yard = 36 inches
1 yard = 3 feets
If 1 feet = 12 inches
4 feets will be ; (12 * 4) inches = 48 inches
If 1 mile = 5280 feets
2 miles will be ; (5280 * 2) = 10,560 feets
If 1 yard = 3 feets
1 2/3 yards will be ; (5 /3) * 3 = 5 feets
If 1 yard = 36 inches
3 1/2 yards will be ; (7 /2 ) * 36 = 126 inches
