Answer:

11 years

Step-by-step explanation:

Set the function f(x) = 100(1.0153)^x = to 118 and solve for x:

100(1.0153)^x = 118

Taking the natural logarithm of both sides, we get:

ln 100 + x ln 1.0153 = ln 118

Then x ln 1.0153 = ln 118 - ln 100, or

= 4.7707 - 4.6052

... which leads to:

4.7707 - 4.6052

x = --------------------------- = 11 years (rounded up from 10.888 )

Complete Question

A newsletter publisher believes that above 41% of their readers own a personal computer. Is there sufficient evidence at the 0.10 level to substantiate the publisher's claim?

State the null and alternative hypotheses for the above scenario.

Answer:

The null hypothesis is $H_o : p \le 0.41$

The alternative hypothesis $H_1 : p> 0.41$

Step-by-step explanation:

From the question we are told that

The population proportion is $p = 0.41$

The level of significance is $\alpha = 0.10$

The null hypothesis is $H_o : p \le 0.41$

The alternative hypothesis $H_1 : p> 0.41$
