A population has a mean of 200 and a standard deviation of 50. Suppose a sample of size 100 is selected. What is the probability

leonid [27]

Answer: 0.9544

Step-by-step explanation:

As per given have ,

Population mean : $\mu=200$

Standard deviation : $\sigma=50$

Sample size : n= 100

We assume that the population is normally distributed.

Let $\overline{x}$ be the sample mean.

Now , the probability that the sample mean will be within ±10 of the population mean will be :-

$P(200-10$

$P(\dfrac{190-200}{\dfrac{50}{\sqrt{100}}}$

$=P(\dfrac{-10}{\dfrac{50}{10}}$

$=P(\dfrac{-10}{5}$

Hence, the required probability is 0.9544.

(1+sinx/cos^2x) = tan^2x + 1 + tanxsecx

mr_godi [17]

#ANSWER#

(1+sinx/cos²x) =tan²x+1+tanx . secx

-> [(1+sinx/cos²x)] = 1/cos²x+sinx/
-> cos²x

-> = sec²x+tan x sec x
-> =tan²x+1+tanx secx
