The equatorial radius of the planet Jupiter is measured 40 times by a process that is practically free of bias. These measuremen
Nina [5.8K]

Answer:

The 93% confidence interval for the equatorial radius of Jupiter is between 71484 km and 71500 km.

Step-by-step explanation:

Sample size of 30 or larger, so we can use the normal distribution to find the confidence interval.

We have that to find our \alpha level, that is the subtraction of 1 by the confidence interval divided by 2. So:

\alpha = \frac{1-0.93}{2} = 0.035

Now, we have to find z in the Ztable as such z has a pvalue of 1-\alpha.

So it is z with a pvalue of 1-0.035 = 0.965, so z = 1.81

Now, find M as such

M = z*\frac{\sigma}{\sqrt{n}}

In which \sigma is the standard deviation of the population and n is the size of the sample.

M = 1.81*\frac{28}{\sqrt{40}} = 8

The lower end of the interval is the sample mean subtracted by M. So it is 71492 - 8 = 71484 km.

The upper end of the interval is the sample mean added to M. So it is 71492 + 8 = 71500 km.

The 93% confidence interval for the equatorial radius of Jupiter is between 71484 km and 71500 km.

Which of the following illustrates the truth value of the given statements?
Ierofanga [76]

Answer:

FT\rightarrow T

Step-by-step explanation:

If p and q are two statements, then you can use the following table to find the value of p\vee q:

\begin{array}{ccccc}p&|&q&|&p\vee q\\ \\T&|&T&|&T\\T&|&F&|&T\\F&|&T&|&T\\F&|&F&|&F\end{array}

If

p: 7 is an even number  - is false, because 7 is not an even number (F)

q: 3 is the square root of 9 - true, because 3 is the square root of 9 (T),

then according to the above table, p\vee q is true.

Correct option

FT\rightarrow T
