A scientist is studying human memory. Subjects are shown a five-digit number for different lengths of time and then must write the number down. The subject either correctly recalls the number or fails to recall it. (Answer using R CODING) The results are as follows:

times <- c(10.73, 9.9, 9.61, 8.7, 8.56, 8.31, 8.18, 7.86, 7.63, 6.99, 6.66, 6.1, 5.92, 5.84, 5.67, 5.64, 5.56, 5.29, 5.1, 5.09, 4.92, 4.81, 2.86, 2.13, 2.05, 1.95, 1.67, 1.67, 1.38, 1.02)

correct <- c(1, 1, 1, 1, 1, 1, 1, 1, 1, 0, 1, 1, 1, 1, 0, 0, 0, 0, 0, 1, 1, 1, 0, 0, 0, 0, 0, 1, 0, 0)

Here, times shows the amount of time given to the student, and correct is a Bernoulli variable, with 1 meaning the number was correctly recalled 0 meaning it was not.

a) Report your p-value, state your null hypothesis, state whether your p-value is significant, and interpret.

b) give a rough estimate for the time required for the number to be correctly recalled with 90% probability

Java Code!!!! A five-digit number is said to be friendly if: the leftmost digit is divisible by 1 and the leftmost two digits are divisible by 2 and the leftmost 3 digits are divisible by 3 and the leftmost 4 digits are divisible by 4 and leftmost 5 digits (the five-digit number itself) is divisible by 5. For example, the number 42325 is a friendly number: 4 is divisible by 1 and 42 is divisible by 2 and 423 is...

The table below gives the number of hours five randomly selected students spent studying and their corresponding midterm exam grades. Using this data, consider the equation of the regression line, yˆ=b0+b1x, for predicting the midterm exam grade that a student will earn based on the number of hours spent studying. Keep in mind, the correlation coefficient may or may not be statistically significant for the data given. Remember, in practice, it would not be appropriate to use the regression line...
