What is the value of the t score for a 95% confidence interval if we take a sample size of 5

The value of t-score for 95% confidence interval and a sample of size 5 is 2.776.

Step-by-step explanation:

The (1 - α)% confidence interval for population mean (μ) in case the population  standard deviation is not known is given by:

Here,

= sample mean

s = sample standard deviation

n = sample size

= critical value.

The information provided is:

The confidence level is, (1 - α)% = 95%.

The sample size is, n = 5.

Compute the t score as follows:

*Use a t-table for the critical value.

Thus, the value of t-score for 95% confidence interval and a sample of size 5 is 2.776.

0

step-by-step explanation:

you can not divide by 0 so 4 ÷ 0 would be 0

0 × 9999 =0

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.
