Answer:

The 80% confidence interval for difference between two means is (0.85, 1.55).

Step-by-step explanation:

The (1 - <em>α</em>) % confidence interval for difference between two means is:

CI=(\bar x_{1}-\bar x_{2})\pm t_{\alpha/2,(n_{1}+n_{2}-2)}\times SE_{\bar x_{1}-\bar x_{2}}

Given:

\bar x_{1}=M_{1}=6.1\\\bar x_{2}=M_{2}=4.9\\SE_{\bar x_{1}-\bar x_{2}}=0.25

Confidence level = 80%

t_{\alpha/2, (n_{1}+n_{2}-2)}=t_{0.20/2, (5+5-2)}=t_{0.10,8}=1.397

*Use a <em>t</em>-table for the critical value.

Compute the 80% confidence interval for difference between two means as follows:

CI=(6.1-4.9)\pm 1.397\times 0.25\\=1.2\pm 0.34925\\=(0.85075, 1.54925)\\\approx(0.85, 1.55)

Thus, the 80% confidence interval for difference between two means is (0.85, 1.55).

Cole said All prime numbers are odd and all composite numbers are even do you agree with cole?
Anit [1.1K]
A prime number is such that it is divisible by only itself and one. ... Two is a prime because it is divisible by only two and one. All the other even numbers are not prime because they are all divisible by two. That leaves only the odd numbers.

Brooke cooked a 4/1/3-pound lasagna in 1/1/3 hours. How many hours per pound did it take to cook the lasagna?
Hitman42 [59]

Answer:

4/13 hours

Step-by-step explanation:

Total pounds of lasagna = 4 1/3 pounds

Total time taken to cook = 1 1/3 hours

How many hours per pound did it take to cook the lasagna?

Hours per pound of lasagna = Total time taken to cook / Total pounds of lasagna

= 1 1/3 hours ÷ 4 1/3 pounds

= 4/3 ÷ 13/3

= 4/3 × 3/13

= 4/13 hours

It will take 4/13 hours to cook each pound of the lasagna
