Answer:
- firstly divide 70 by 15 and when the product came multiply it with 39
Step-by-step explanation:
70 ÷ 15 = 4.66
4.66 × 39 = 181.974
Answer:
Yes, we can conclude that the population standard deviation of TV watching times for teenagers is less than 2.66
Step-by-step explanation:
H0 : σ² = 2.66²
H1 : σ² < 2.66²
X²c = (n - 1)*s² ÷ σ²
sample size, n = 40
Sample standard deviation, s = 1.9
X²c = ((40 - 1) * 1.9²) ÷ 2.66²
X²c = 140.79 ÷ 7.0756
X²c = 19.897
Using a confidence level of 95%
Degree of freedom, df = n - 1 ; df = 40 - 1 = 39
The critical value using the chi distribution table is 25.6954
Comparing the test statistic with the critical value :
19.897 < 25.6954
Test statistic < Critical value ; Reject the Null
Hence, we can conclude that the population standard deviation of TV watching times for teenagers is less than 2.66

Answer:
The sale price of a ticket from Austin to Phoenix for someone under 12 is $49.70
Step-by-step explanation:
Let
x----> the sale price of a ticket from Austin to Phoenix for someone under 12
we know that
100%-65%=35%=35/100=0.35
so
x=0.35*($142.00)
x=$49.70
