### I need to find the a 95% confidence interval estimate for population mean. My SD is 100, sample sz. is 64, and sample mean is 350.

First you need the Std Error of the mean value, a measure of the dispersion of that mean value.

SE = sample std deviation / sqrt (sample size)
= 100 / sqrt (64)
= 100 / 8
= 12.5

Then we use a figure for the number of std errors either side of the mean value, which make up a 95 % confidence interval. This is ± 1.96 std errors, from tables of the Normal Distribution.

So the confidence interval is

350 ± 1.96 * 12.5 or

374.5 to 325.5
.

### Construct a 99 confidence interval for the population mean if my sample mean is 125, and Std Dev is 8, and population size is 64

First you need the Std Error of the mean value, a measure of the dispersion of that mean value.

SE = sample std deviation / sqrt (sample size)
= 8 / ? 64
= 1

Then we use a figure for the number of std errors either side of the mean value, which make up a 99 % confidence interval. This is ± 2.58 std errors, from tables of the Normal Distribution.

So the confidence interval is

125 ± 2.58 * 1 or

127.58 to 122.42
.

### When i try to do a inverse function e.g sin^-1 90 i keep getting error 2 can anyone help me

It seems that you are trying to calculate the inverse sine (arcsine) of 90. However the domain of definition of the arcsine function is the closed interval [-1, 1]. Any value outside of this interval will result in an error.

### Ours's a hp color laserjet 4700dn ; the message is 59.30 error ; we bought the machine in the year 2007 what do you suggest?

59.30 states it's the:Fuser motor startup error
Based on the service manual here are the steps to follow:
Fuser motor error
1. Reconnect the connectors J4605 for
the fuser motor and J1024 on the DC
controller PCB.
2. Run the component test to verify that
the fuser motor is working correctly.
3. Replace the fuser motor.

How to preform the component test below
2. Press to highlight DIAGNOSTICS.
3. Press to select DIAGNOSTICS.
4. Press to highlight COMPONENT TEST.
5. Press to select COMPONENT TEST.
6. Select the component test Fuser motor. Use this test to rotate the fuser motor and drive gears.
Menus cannot be opened during component tests, so serves the same function as the Stop button.

• The DC controller determines the fuser motor failure and notifies the formatter of an error status when it encounters the following conditions.
• Fuser motor start-up abnormality. The interval of the fuser motor speed detection signal does not reach the specified interval after 1.5 seconds of the fuser motor drive start.
• Fuser motor rotation abnormality. The interval of the fuser motor speed detection signal stays at an irregular interval for two seconds and longer after it reaches the specified interval.

I've attached a screen shot of where the fuser motor is located It is # 8.

### I have an E500 that shows Card Error replacing a new card does not solve the problem having approched sevral repairer's this could be expensive to repair could you advise wether this is the case or...

Card error usually means either the slide switch on an SD/SDHC card is in the locked position or your memory card needs to be formatted in the camera. This will erase it so download any pics first using a card reader if necessary.

### I had windows xp running on it but then my computer went down.ive tried reinstalling windows sevral time with differrent disks but it keeps saying there a 14 error

Hi,

14 Error is related to the manual reboot required once the Drivers or operating system has been newly installed.

So after reinstalling the operating system, install all the require drivers for the hardware and reboot manually it will fix the issue.

### Steady red status light on NEC VT45 projector. Would not POWER ON. LAMP was replaced with a new one

the power supply on that model seem to go bad after a while. the caps aren't properly reted it's power needs. they dry up. if you are good at soldering, replace c1 on the board (big cap) with a cap that has a slightly higher voltage rating. or replace the whole power supply. you might not be able to get one from nec, but you can try www.projectordoctor.com
