Let p be a population proportion. Consider the problem of testing H0 : p ≥ 0.4 based on a simple random sample of size n.(a) Sta

te the test statistic and its approximate distribution when p = 0.4 and n large enough.(b) State the rule for rejecting H0 at significance level 1% and compute its power function.(c) What is the smallest n such that the power is at least 70% when p = 0.35?(d) What is the p-value if the observed value of the sample proportion is 36% and n = 100? Is H0 rejected at significance level 1%?

Likurg_2 [28]

Answer:

The exponential growth function is P=145380e^{0.04103t}

Step-by-step explanation:

Given: The population of a certain city was 145,380 in 2000 and 219,135 in 2010.

To find: exponential growth function that models the growth of the city

Solution:

The exponential growth function is given by P=P_0 e^{kt}

Here, P denotes total population after time t

P_0 denotes initial population

k denotes rate of growth

t denotes time

As P(0)=145,380,

145380=P_0e^{0}\\145380=P_0\\P=145380e^{kt}

As P(10)=219135

219135=145380e^{10k}\\e^{10k}=\frac{219135}{145380}\\=1.507326\\k=\frac{1}{10}\ln (1.507326)\\=0.04103\\\Rightarrow P=145380e^{0.04103t}

A random number generator is selecting numbers in the range 1 through 50. What is the probability that the random number generat
kati45 [8]

Answer:

7,14,21,28,35,42,49 are all dividible by 7. That are 7 Numbers. However we are looking for All the Numbers that are not a multiple of 7.

So 50-7=43.

There are 43 Numbers which are not a multiple of 7.

So 43/50=0.86

The probability is 0.86 or a 86% chance that the generator will select a Number which is not a multiple of 7.
