When Doris Lessing published The Golden Notebook
ValentinkaMS [17]

There was an error in A.

<h3>What is The Golden Notebook?</h3>

The Golden Notebook is a 1962 book by Doris Lessing, a British author. It investigates mental and societal breakdown, much like her two succeeding books, which Margaret Drabble referred to as Lessing's "inner space fiction" in The Oxford Companion to English Literature. In addition to an extensive investigation of communism and the Communist Party in England from the 1930s to the 1950s, the novel also examines the nascent sexual revolution and women's liberation movements. It also contains anti-war and anti-Stalinist undertones. The Golden Notebook was listed among the top 100 English-language books published since 1923 by TIME magazine in 2005. Other languages that it has been translated into include French, Polish, Italian, Swedish, Hungarian, and Hebrew.

How do you solve this problem? population proportion is to be estimated from a sample of 400 with a sample proportion of 0.1. Ap
Ivan

Answer:

(0.0706, 0.1294)

Step-by-step explanation:

Confidence interval of a proportion is:

CI = p ± CV × SE

where p is the proportion,

CV is the critical value (z score or t score),

and SE is the standard error.

The sample is large enough to estimate as normal.  For 95% confidence level, CV = z = 1.96.

Standard error for a proportion is:

SE = √(pq/n)

SE = √(0.1 × 0.9 / 400)

SE = 0.015

The confidence interval is:

CI = 0.1 ± (1.96)(0.015)

CI = (0.0706, 0.1294)

Round as needed.
