Asurvey of nonprofit organizations showed that online fundraising has increased in the past year. based on a random sample of 50 nonprofit organizations, the mean one-time gift donation in the past year was $62, with a standard deviation of $9. test whether there is evidence that the mean one-time gift donation is different than $60?

Check the explanation below.

Step-by-step explanation:

Hello!

The study variable is X: one-time online fundraising that a nonprofit organization has received.

Sample:

n= 50

sample mean X[bar]= $62

Standard deviation S= $9

You are interested in testing the average one-time donation is different than $60. Symbolically: μ ≠ 60

The hypothesis is:

H₀: μ = 60

H₁: μ ≠ 60

You didn't stat any significance level, I'll use a level of 5%

The critical region and the p-value for this test are two-tailed. Since all the available information is from the sample, assuming that the variable has normal distribution I've chosen the Student-t statistic:

t= X[bar] - μ ~ t

         S/√n

t= 62 - 60  = 1.57

    9/√50

The p-value for t=1.57 is 0.1228

Since the p-value: 0.1228 is greater than the significance level of 5%, the decision is to reject the null hypothesis. This means that the average one-time gift online fundraising that a nonprofit organization received is equal to $60.

I hope it helps!

75

step-by-step explanation:

you do x-29=46 (the number of cantaloupes sold)

in order to find x, you have to find what minus 29 equals 46, meaning you'd have to add 29 to 46.

29+46=75

if you replace x with 75, the equation looks like:

75-29=46

x=75
