(WILL GET BRAINLESS IF YOU EXPLAIN)

Vaselesa [24]

Answer:

Quran Surah Fatir 35:5

Step-by-step explanation:

What this verse is trying to say is, don't let this life you are living right now mislead you and misguide you! For example, you see non-believer doing zina, drinking alchoal, or doing bad sins. These are some of the major distractions and the disbelievers who do these types of stuff will try to mislead you by making you do this also with them.

(I want to clarify it's better if you go to an Imam or somebody knowledgeable and ask them because they will help you explain this verse in a more understandable way. I tried but it's better to check an Imam!)

Hope this helped!

Answer:

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

Step-by-step explanation:

The (1 - α) % 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 t-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).
